Two positive charges of 6.3 x 10-6 C are separated by 0.50 m. What force exists between the
charges?
A negative charge of – 2.0 x 10-4 C and a positive charge of 8.0 x 10-4 C are separated by
0.30 m. What is the force between the two charges?
Two negative charges of – 5. 2 x 10-5 C exert a repulsive force of 8.15 N on each other. How
far apart are they from each other?
A charge of 4.0 x 10-5 C is attracted by a second charge with a force of 350 N when the
separation is 10.0 cm. Calculate the size of the second charge.
A force of 118 N exists between a positive charge of 2.8 x 10-5 C and a negative charge of
7.3 x 10-6 C. What distance separates the charges?
