Task id12402

Suppose that the force acting between two point charges depends on the distance between them as 1/(ra). How will a point charge behave when placed inside (not necessarily in the center) of a sphere uniformly charged over the surface. At the initial moment of time, the point charge is at rest. Consider the cases when a) a=sqrt(5) , b) a=sqrt(7) , c) a=sqrt(2) , d) a=sqrt(3) .
