Question

A particle of mass 200 gm executes S.H.M. The restoring force is provided by a spring of force constant 80 N / m. The time period of oscillations is.

• A. 0.31 sec
• B. 0.15 sec
• C. 0.05 sec
• D. 0.02 sec

Answer 1

The correct option is A

0.31 sec

T = $2\pi \sqrt{\frac{m}{k}}=2\pi \sqrt{\frac{0.2}{80}}=0.31sec$
