Four rigid rods AB BC CD and DA each of linear mass density and length a are connected rigidly to form a square frame This system is placed in an XYZ space as shown in the figure such that it can freely rotate about an axis kk parallel to z axis The plane ABCD is on the y z plane The rods AB and CD are carrying charges of linear charge density p and p respectively An electric field is existing in the space which is E Ej If the wire frame is rotated by a small angle 40 about the kk axis and released Find the time in second required by the frame ABCD to regain its original position for the first time 1 kq m a 2m p 1 3 C m E N C k Z YOU C k
