Solver the all parts of following problem given below:

Problem: Two identical conducting spheres, fixed in place, attract each other with an electrostatic force of -0.3790 N when separated by 50 cm, center-to-center. The spheres are then connected by a thin conducting wire. When the wire is removed, the spheres repel each other with an electrostatic force of 0.1820 N.

Part A: What were the initial charges on the spheres? Since one is negative and you cannot tell which is positive or negative, there are two solutions.

Part B: Take the absolute value of the charges and enter the smaller value here? What is the Larger Value?

I am not able to get the correct solution please help me.
