Question

A body of mass 100 g is revolving in a
horizontal circle. If its frequency of rotation is 3.5 r.p.s. and radius of circular path is 0.5 m, the angular speed of the body is ?

(A) 18 rad/s (B) 20 rad/s
(c)22 rad/s (D) 24 rad/s
​

Answer 1

Answer:

Correct answer is 22 rad/s

Explanation:

n=3.5 r. p. s.

ω =2πn =2×π×3.5 =7 ×22/7 which is approximately equal to 22 rad/s.

Answer 2

Answer:

the answer is approximately 22 rad/s
