Two point charges, q1 and q2, are separated by a distance r. if the magnitudes of both charges are doubled and their separation is also doubled, what happens to the electrical force that each charge exerts on the other one?

The electrical force that each charge exerts on the other one will be same .

Explanation:

Given that,

Two point charges, q₁ and q₂, are separated by a distance r.

The electric force will be

If the magnitudes of both charges are doubled and their separation is also doubled.

The new electric force will be

Therefore, We can say that the new electric force F' will be same as the electric force F.

Hence, The electrical force that each charge exerts on the other one will be same .

the minimum amperage that the current in this wire would have to have so that its weight is completely supported by the magnetic force due to earth's field, assuming that no other forces except gravity act on it

energy can be converted from one form to another, but it cannot be created or destroyed in ordinary chemical or physical means. do not understand what you are asking but hope this
