QUESTION #26 Electric Potential Energy
Consider two identical metallic spheres of radius R each having charge Q and mass m. Their centers have an initial separation of 4R. Both the spheres are given an initial speed of u towards each other. The minimum value of u, so that they can just touch each other is: (Take k= 14πε₀ and assume kQ²>Gm² where G is the Gravitational constant)
