Question

21. A particle with radius R e moving in a circular path with constant speed. The time period of the
particle is T .calculate the time for the following after t =T6
What is the average speed of the particle
(a)R/T
b)πR/6T
c)2πR/3T
d)2πR/T​

Answer 1

Answer:

2πR / T

Explanation:

constant speed = {(distance covered) / (Time taken)}

= {(1 circumference) / (Total time)}

= {2πR / T}

hence avg. speed = constant speed of particle = {2πR / T}
