Two charges q1 and q2 exert a force of 20 N on each other. If the charge of q1 is doubled, what will the new force be? 1) 40N 2) 80N 3) 20 N 4) 10 N

Given :

Two charges q1 and q2 exert a force of 20 N on each other.

To Find :

If the charge of q1 is doubled, what will the new force be?

1) 40 N 2) 80 N 3) 20 N 4) 10 N

Solution :

We know, electrostatic force between two charges is given by :

Here, F = 20 N.

Now, if is doubled :

Therefore, if the charge of q1 is doubled, new force will be 40 N.

answer: the direction of the wind is expressed as the direction from which the wind is blowing. for example, easterly winds blow from east to west, while westerly winds blow from west to east.
