Part complete a potential energy function is given by u(x)=(3.00n)x−(1.00n/m2)x3. at what position or positions is the force equal to zero?

Given,

Potential energy, U(x)=3x-x^{3}

Force is given by, F=dU/dx

F= d(3x-3x^{3})/dx

=3-3x^{2}

For F=0 N,

3-3x^{2} =0

3x^{2} =3

x=√1

Therefore, at x=+1 and x= -1, the force for the given potential energy is zero.

the moon affects the earth gravitation ally, causing certain motions of that body and also producing tides in its ocean and atmosphere. the tidal wave in our atmosphere is, however, far too minute to be an effective cause in any known meteorological phenomenon.
