Questions
The magnitude of displacement of a particle moving in a circle of radius a with constant angular speed varies with time t is
detailed solution
Correct option is B
In time t particle has rotated an angle θ = ωt. Displacements= PQ = QR2+PR2s = (a sin ωt)2+(a-a cos ωt)2s = 2a sin ωt2Talk to our academic expert!
