NEET 2016 Physics question
A uniform circular disc of radius 50 cm at rest is free to turn about an axis which is perpendicular to its plane and passes through its centre. It is subjected to a torque which produces a constant angular acceleration of . Its net acceleration in at the end of 2.0 s is approximately:
Answer: (1)
Solution
The net acceleration of a point on the rim has a tangential and a centripetal (radial) component. Angular velocity after 2.0 s (starting from rest): . Centripetal acceleration: $ =
