Two identical conducting spheres, fixed in place, attract each other with an electrostatic force of 0.102 N when their center-to-center separation is 74.8 cm. 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 0.0373 N. Of the initial charges on the spheres, with a positive net charge, what was (a) the negative charge on one of them and (b) the positive charge on the other? (Assume the negative charge has smaller magnitude.) (a) Number (b) Number i Units Units

Expert Solution
Step 1

Given,

two identical spheres, fixed in place, attract each other with an electrostatic force of attraction of attraction 

F1=0.102 N

and the separation

d=74.8cm=0.748m

The spheres are then connected by conducting wires. When the wire is removed the spheres repel each other with an electrostatic force of

F=0.0373 N
