Question

# A particle is moving in a circle of radius R with constant speed. The time period of the particle is T. In a time t=T6   16. Average speed of the particle isπR6T2πR3T2πRTRT

Solution

## The correct option is C 2πRTIn t=T6, particle will travel 16th of circle. Hence,  Average speed=arcPQtime   =2πR6(T6)=2πRT Alternatives: Since, average speed remains constant and the time required to make a full circle is T. Hence, Average speed=distanceTime=2πRT
