Net force acting on the rod is 1 2qE leftwards 3 Zero 1 2T 3 2 9 m AO me 2qE A light insulating rod AB with two small identical metal balls connected to its ends is placed in a uniform electric field with its length parallel to the electric field Charges on the balls are q and q as shown mass of each ball is m and length of the rod is Assume that the space is gravity free 2ml qE 2 4 2 If the rod is rotated in anticlockwise direction by angle 90 from the position shown torque acting on the rod will be 1 qEl clockwise 2 2qEl anticlockwise 3 qEl anticlockwise 4 2qEl clockwise 38 If the rod is slightly disturbed from the position shown it oscillates with time period 4 FO q m 2 2T Em 2qE rightwards 2qE upwards B me qE E me 4gE
