A particle completes 10 revolutions in 5s in a circular path of radius 1.5m. What is its linear speed?
Frequency f=nt=105=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 12 m/s as the result, so option A is correct.
