A block of mass M is connected to a string and rotated with uniform angular speed on a circular track of radius R in the horizontal plane with coefficient of kinetic friction Then choose the correct statement s e is angle between the string and movement of the hand A Work done by the string in one revolution is the negative of work done by friction B Work done by the hand on the string does not depend on angle 0 C Work done by the hand on the string is negative of the work done by friction D Work done by the string on the block is u Ma 2 R
