Question

If two chargesattract each other,the explanation forthis phenomenon isthat

Answer 1

The coloumb force of attraction between the charges is negative.

`F=(q_1q_2)/(4\pi\epsilon_or^2)`

If the two charges are of opposite sign.

Then,

`F=-(q_1q_2)/(4\pi\epsilon_or^2)`

Here negative sign is indicating the attraction between the charges.

If both the charges are of same sign,

Then,

`F=+(q_1q_2)/(4\pi\epsilon_or^2)`

Positive sign representing the repulsion between the charges.
