## Homework Statement

002 (part 1 of 2) 2.0 points

Two identical conducting spheres are placed with their centers 0.3 m apart. One is given

a charge of +1.3 × 10^−8 C and the other a charge of 1 × 10^−9 C. Find the electric force exerted on one sphere by the other. The value of the Coulomb

constant is 8.98755 × 109 N · m^2/C^2.

Answer in units of N.

003 (part 2 of 2) 2.0 points

The spheres are connected by a conducting wire. After equilibrium has occurred, find the

electric force between the two spheres.

## The Attempt at a Solution

So, I input all of the numbers into the formula as shown, but the homework system won't accept the answer. Any clue as to why?

As to the second part, I assume I total the charges and divide it by two, then use that in the equation as both charges...Right?
