3F = dU/dx .............
F = asin(ax)U1 .....................
for very small ax ..... sin(ax) = ax
F = a2 x U1 ...........
let particle have ,mass m ......
mw2x = a2 x U1
w = √a2 U1/m ...
the potential energy of a particle executing S.H.M along the x- axis is given by U = U1 - U1 cos(ax). wat is the period of oscillation ??????????????????????????????????????????????????
