A charge +Q is fixed. Another charge +2q and mass M is projected from a distance R from the fixed charge at and angle 30 with the horizontal towards the fixed charge (like a projectile) at a speed of vFind the minimum separation between the two charges if the velocity becomes 1/√3 times of the projected velocity at this moment (assume gravity to be absent)ANSWER : sqrt(3) R/2, i have been trying energy conservation but unable to get this answer plz.. help ..thnx in advance
