In the figure below a neutral insulating disk of mass M and radius R is pivoted at the center A small charge q having negligible mass is fixed to one edge and a charge of q having negligible mass is fixed to the opposite edge so that the line between the two charges makes a small angle with an applied uniform electric field E as shown A The torque on the disk is 2qRE sine B The angular frequency with which the disk oscillates C The angular frequency with which the disk oscillates D The torque on the disk is RE sine 4Eq MR 2Eq MR 9 M
