Afixed system of charges exerts a force of magnitude 22 n on a 4.0 c charge. the 4.0 c charge is replaced with a 8.0 c charge. what is the exact magnitude of the force (in n) exerted by the system of charges on the 8.0 c charge? do not include units with your answer.

44 N

Explanation:

The electrostatic forces between two charges is given by:

where

k is the Coulomb's constant

q1 and q2 are the two charges

r is their separation

We notice that the force is directly proportional to the charges.

In this problem, initially we have a force of

F = 22 N

on a q2 = 4.0 C, exerted by a charge q1.

If the charge is doubled,

q2 = 8.0 C

This means that the force will also double, so it will be

hi there!

out of the two, (b) precision would be more reasonable.   however, both a and b could be pretty reasonable.
