A particle of mass m and charge q is fastened to one end of a string of length. The other end of the string is fixed to the point O. The whole sytem liles on as frictionless horizontal plane. Initially, the mass is at rest at A. A uniform electric field in the direction shown in then switfched on. Then

A particle of mass m_(1) is fastened to one end of a string and one of m_(2) to the middle point, the other end of the string being fastened to a fixed point on a smooth horizontal table The particles are then projected, so that the two portions of the string are always in the same straight line and describes horizontal circles find the ratio of tensions in the two parts of the string
