An unknown charge exerts an attractive force of 4.23 E 13 N. If these charges are separated by 8cm, what is the magnitude of the unknown charge if the other charge has a magnitude of 10C

Since there is attraction force between two charges so the other charge must be - 3C

Explanation:

As we know that the force between two charges is given by formula

here we know that

also we know that

r = 8 cm

now we have

so we have
