Out of two copper spheres of the same size, x is hollow while y is solid. If they are charged at the same potential, what can be said about the charges on them?

Options

  1. ASphere x will have more charge
  2. BSphere y will have more charge
  3. CCharge on both the spheres are equal
  4. DCharges on both the sphere are zero

Correct answer

C. Charge on both the spheres are equal

Step-by-step solution

Charges on a conductor accumulate only on the surface. Therefore, a hollow sphere or a solid one, both will have exact same charge distribution and the exact same charge for given potential. ∴ Charge on both spheres is equal.
