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\(_{−1}\)
Verified Correct Answer: A.
Physical Principles & Numerical Solution
1 cycle = 360^\circ = 2\pi rad
∴ 50 cycle = 2 \pi rad \times 50 = 100 \pirad
∴ = angular speed = 50 cycles per seconds = 100 \pi rads\(_{−1}\)
