Rotational MotionHard
Question
A uniform solid disc of mass 1 kg and radius 1m is kept on a rough horizontal surface. Two forces of magnitude 2 N and 4 N have been applied on the disc as shown in the figure. Linear acceleration of the centre of mass of the disc is if there is no slipping.
Options
A.4 m / s2
B.2 m / s2
C.1 m / s2
D.zero
Solution
Taking torque about contact point, τ = 4 × R - 2 × 2R = 0, Fnet = 0
