A positively charged thin metal ring of radius R is fixed in the xy plane its centre at the origin 0.A negatively charged particle P is released from rest at the point (0, 0, z0) where z0 > 0. Then the motion of P is (a) periodic, for all values of z0, satisfying 0 < z0 < 8(b) simple harmonic, for all values of zo satisfying 0 < z0 = R(c) approximately simple harmonic, provided z0 << R(d) such that P crosses O and continues to move along the negative z axis towards z = - 8
