Question

A particle completes 6 revolutions in 3s in a circular path of radius 1m. What is its linear speed?

Options

Choose one · Correct answer highlighted

Explanation

Frequency f=nt=63=2Hz. As per NCERT Chapter 3, equations v=u+at, s=ut+½at², v²=u²+2as describe uniformly accelerated motion. Applying correct signs and units gives 8 m/s as the result, so option A is correct.
