What is the speed of a body vibrating at 50 cyclic per second
-
A.
100 πrads(_{−1}) -
B.
200 πrads(_{−1}) -
C.
50 πrads(_{−1}) -
D.
400 πrads(_{−1})
Correct Answer: Option A
Explanation
1 cycle = 3600 = 2π rad
∴ 50 cycle = 2 π rad × 50 = 100 πrad
∴ = angular speed = 50 cycles per seconds = 100 π rads(_{−1})
