A positive charged particle of charge q and mass m is suspended from a point O by a string of length In the space a uniform horizontal electric field E exists The particle is drawn aside so that the string becomes vertical and then it is projected horizontally with velocity v such that the particle starts to move along a circle with same constant speed v A tension in string is mg qE qE B tension in string is mg C kinetic energy of mass is q E 2mg 5 D kinetic energy of mass is mg q E
