Answer 1

Answer:

Answer 2

The force on a unit charge placed at the centre of the sphere with an uniform spherical surface charge distribution of Q is equal to zero.

• The force on a charge placed at a point is the product of the charge and the electric field at that point.
• The electric field at any point inside a spherical shell with uniform charge distribution is equal to zero due to the shell's theorem which can be verified using Gauss law.
• Therefore, since field at the centre is equal to zero, the electric force on the charge is also equal to zero
