What is the charge of the hollow metal sphere?
A hollow metal sphere is electrically neutral (no excess charge).
Which location will have the greatest electric field strength?
Electric field strength is greatest where the lines are closest together and weakest where lines are furthest apart.

Is a hollow metal sphere a conductor?
But since the sphere is made of metal (which are usually good conductors) so there will be a flow of current between these two points until the potential difference between them vanishes. So in equilibrium i.e. when no current is flowing, electric field inside sphere should be zero.
What is hollow sphere?
A hollow sphere is a ball that has been hollowed such the an equal thickness wall creates anopther internal ball within the external ball.
Does a metal sphere have a charge?
A metal sphere is electrically neutral. It is touched by a positively charged metal rod. As a result, the metal sphere becomes charged positively.
Which area is positively charged?
A proton is a positively charged particle located in the nucleus of an atom. An electron has 11836 times the mass of a proton, but an equal and opposite negative charge. An elementary charge — that of a proton or electron — is approximately equal to 1.6×10-19Coulombs.
Why can you use either a positive charge or a negative charge to move the positively charged puck?
why can you use either a positive charge or negative charge to move the positively charged puck? if you were to use a positive charge that would repel the puck, but if you were to use a negative charge it would attract.
Where is the electric field equal to zero?
Explanation: To find where the electric field is 0, we take the electric field for each point charge and set them equal to each other, because that’s when they’ll cancel each other out. The ‘s can cancel out. Therefore, the electric field is 0 at .
Which has more charge solid or hollow sphere?
A solid sphere does not retain more charge than a hollow sphere of the same diameter, because charge resides on the outer surface of a conductor, and outer surface areas of the two spheres are equal.
Which has more capacitance to store charge hollow sphere or conducting sphere?
Answer. All else being equal, a hollow and a solid conducting sphere hold the same amount of charge. Q = CV, where Q is the amount of charge, C is the ‘capacitance’ of the capacitor and V is the voltage applied between the conducting plates or surfaces of the capacitor.

What is hollow non conducting sphere?
A hollow non conducting sphere of radius R has a positive charge q uniformly distributed on its surface. The sphere starts rotating with a constant angular velocity ′ω′ about an axis passing through center of sphere, as shown in the figure. Then the net magnetic field at center of the sphere is.
What is the formula for hollow sphere?
(a) Volume of a solid sphere = (4/3)πr3, (b) Volume of a hollow sphere = (4/3)π(R3 – r3). Let us understand more about the volume of a sphere. Explanation: The volume of a sphere is the measure of space that can be occupied by a sphere.
What is a hollow cylinder?
A hollow cylinder is one which is empty from inside and has some difference between the internal and external radius. Examples of a hollow cylinder: tubes, circular buildings, straws, etc.
What is area of hollow sphere?
The formula for the surface area of a hollow hemisphere is, TSA of hollow hemisphere = 3πR2 + πr2.
When a positively charged sphere is brought near a metallic sphere?
Suppose a positively charged sphere is brought near an unchanged metallic sphere, then on nearer surface of the uncharged sphere, negative charge is induced and on farther will obsrved between these two shperes.
How do you charge an object positively?
An electrical charge is created when electrons are transferred to or removed from an object. Because electrons have a negative charge, when they are added to an object, it becomes negatively charged. When electrons are removed from an object, it becomes positively charged.
How can a material become positively charged?
An object is charged when electrons are added or removed from it. When the electrons are removed the object becomes positively charged.
Which particles carry a positively charged?
Protons and Electrons
A proton carries a positive charge (+) and an electron carries a negative charge (-), so the atoms of elements are neutral, all the positive charges canceling out all the negative charges. Atoms differ from one another in the number of protons, neutrons and electrons they contain.

Which objects are attracted by a positively charged object?
Any charged object – whether positively charged or negatively charged – will have an attractive interaction with a neutral object. Positively charged objects and neutral objects attract each other; and negatively charged objects and neutral objects attract each other.
What do you call the positively charged particles?
Protons are positively charged particles found within atomic nuclei. Rutherford discovered them in experiments with cathode-ray tubes that were conducted between 1911 and 1919. Protons are about 99.86% as massive as neutrons according to the Jefferson Lab. The number of protons in an atom is unique to each element.
