1 A long plank P is placed on a horizontal frictionless surface and connected to two springs of spring constant k and 2k respectively A cylinder of mass m is placed on the plank The plank is displaced towards right positive direction and released at t 0 and it oscillates with amplitude A The cylinder does not slip on the plank during the oscillation m A 2k mmmm 2m k mmmmm The maximum friction force acting on the cylinder during the oscillation is 2kA 3kA 2kA A 3 KA B C D 3 7 7 The friction force acting on the cylinder as a function of time is shown as Take the right side as positive NAAA D
