Physics

Two identical conducting spheres, fixed in place, attract eachother with an electrostatic force of -0.6825 N when separated by 50cm, center-to-center. The spheres are then connected by a thinconducting wire. When the wire is removed, the spheres repel eachother with an electrostatic force of 0.1986 N. What were theinitial charges on the spheres? Since one is negative and youcannot tell which is positive or negative, there are two solutions.Take the absolute value of the charges and enter the smaller valueAND larger value.
