Question

Why potential energy is zero at infinity?​

Answer 1

Explanation:

The only reason we choose it to be zero at infinity is because it's convenient - nothing less, nothing more. If two objects are separated by infinity, then they cannot interact, because electromagnetic force will never reach opposite side, thus potential energy is zero, even if electromagnetic force is not zero.
