What would be the kinetic energy k2q of charge 2q at a very large distance from the other charges? express your answer in terms of q, d, and appropriate constants?

Explanation:

At the corner of the square, the potential energy of interaction of other charges with the charge 2q  is given by

So

Also, since

The initial energy of the system is given by;

Since

, the final energy of the system is obtained by

From the law of conservation of energy,

Therefore,

the ima (higher than 1m) will be greater than the ima with the height of 1m.
