7 A bead is connected with a fixed cylinder of radius R by an inextensible massless string fR in a smooth horizontal plane If the bead is pushed with a velocity 2 of length v perpendicular to the string The bead moves in a horizontal curve and consequently collapses on the surface of cylinder after a time t Then RI Top View A Work done by the string on the bead is mv B The average speed of the bead is v during the time t C During motion before hitting tension in the string will increase continuously D Kinetic energy of the bead increases gradually
