MHT CET 2024 Physics question
A particle at rest starts moving with a constant angular acceleration of rad/s in a circular path. The time at which magnitudes of its centripetal acceleration and tangential acceleration will be equal, is (in second)
Answer: (C)
Solution
Starting from rest with constant angular acceleration , the angular speed is . Centripetal acceleration and tangential acceleration . Setting gives
