Rotational Motion · Rotational dynamics
A solid sphere of radius 4 cm and mass 5 kg is rotating (rotation axis is passing through the centre of the sphere) with an angular velocity of 1200 rpm. It is brought to rest in 10 s by applying a constant torque. The torque applied and the number of rotations it made before it comes to rest are and respectively.
- (1) Nm, 100
- (2) Nm, 50
- (3) Nm, 50
- (4) Nm, 100
