Question

A solid sphere and a hollow sphere of equal diameters are raised to the same potential, then

1)hollow sphere has more charge 2)both have equal charge 3)only hollow sphere has charge 4)solid sphere has more charge

Answer 1

Explanation:

2)both have equal charge

hope it is helpful to you

Answer 2

Answer: both have equal charge

Explanation: As both the spheres have equal radii, they have the same capacitance. When charged to the same potential, they will have the same charge.

As the potential V of the solid sphere or hollow sphere of the same radii R and holding the same charge Q is given by, $V=\frac{Q}{4\pi E_{0}R }$.

As the capacitance C of each of the spheres is given by, C = $\frac{Q}{V}$= 4πεoR

Now the Capacitance is the physically charged holding capacity of the object. In a solid sphere or hollow sphere, a charge is always residing on the surface.

Hence, the correct answer is both have equal charges.
