Hi aspirant, In classical mechanics, a central force on an object is a force that is directed towards or away from a point called center of force. Not all central force fields are conservative or spherically symmetric. However, a central force is conservative if and only if it is spherically symmetric or rotationally invariant

Also the last two forces are called central forces as they act along the line joining the centres of two charged/magnetized bodies. A central force is conservative if and only if it is spherically symmetric.

Thank You.
