JEE Main 2026 Physics question
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 and assume where G is the Gravitational constant)
Answer: (1)
Solution
Using energy conservation between initial separation 4R and final separation 2R, .
