A non conducting sphere of radius 10 cm has a charge 3 mC distributed uniformly throughout its volume A bullet having charge 3 mC and mass 10g fired from the surface of the sphere along the diameter directly towards its centre Assuming the sphere to be fixed and neglecting any forces other than electrostatic force the minimum velocity of the bullet so that it can emerge from the other side of the sphere is a 3 10 m s b 3 x 10 m s c 9 10 m s d 9 10 m s
