Question

Slope of Force-position curve of a particle undergoing S.H.M is -4,find the mass of the particle if it has a time period of 0.2s ?

Answer 1

`4.053 g`

Explanation:

equation of S.H.M is `F=-momega^2x`

So,slope `=-momega^2=-4` (given) (where, `m` is its mass)

We know, `omega=(2pi)/T=31.416 rads^-1`

So, `m=4/omega^2=0.004053 Kg=4.053 g`
