The following figure shows a block of mass m suspended from a fixed point by means of a vertical spring. The block is oscillatting simple harmonically and carries a charge q. There also exists a uniform electric field in the region. Consider four different cases. The electric field is zero in case 1, mg/q downward in case 2, mg/q upward in case 3, and 2mg/q downward in case 4. The speed at mean position is same in all cases. Select the correct alternative (s).
