Question

The potential at the point where the field is zero is-Gm/Rx. Find x
​

Answer 1

In fact, the X-point lies at a saddle of the effective potential, i. e., ... in an X-configuration at a) = Rx and z=0, which gives the X-point and the X-wind their ... of X make a 60° angle with the upper and lower surfaces of a flathorizontal disk (see Fig. ... By definition, magnetic fields are not strong enough to truncate the disk until R.
