SUPPOSE AN ELECTRON IS ATTRACTED TOWARDS ORIGIN BY A FORCE K/R WHERE K IS A CONSTANT AND R IS THE DISTANCE OF THE ELECTRON FROM THE ORIGIN. BY APPLYING BOHR MODEL TO THIS SYSTEM THE RADIUS OF THE nth ORBITAL OF THE ELECTRON IS FOUND TO BE Rn and THE KINETIC ENERGY OF THE ELECTRON TO BE Tn THAN
WHY Tn is independent of n, Rn directly proportional to N
