Questions
P is a point at a distance r from the centre of a solid sphere of radius a. The gravitational potential at P is V. If V is plotted as a function of r, which is the correct curve ?
detailed solution
Correct option is C
For a solid sphere gravitational potential is given byTherefore inside a solid sphere V changes parabolically with r and outside the solid V - r graph is a rectangular hyperbolic.Hence option - (3) is correct.Talk to our academic expert!
