A body of mass `1//4 kg` is in `SHM` and its displacement is given by the relation `x = 0.05 Sin(20t +(pi)/(2))m`. If `t` is in seconds, the maximum force acting on the particle is

A

5N

B

2.5N

C

10N

D

0.25N

Text Solution

Verified by Experts

The correct Answer is:
A
`a_(max) = omega^(2)A = (20)^(2) (0.05) = 20`
`F_(max) = (1)/(4) xx 20 = 5N`
