Question: Two identical point charges in free space are connected by a string 7.6 cm long. The tension in the string is 0.21 N. (a) Find

Two identical point charges in free space are connected by a string 7.6 cm long. The tension in the string is 0.21 N.

(a) Find the magnitude of the charge on each of the point charges.

(b) Using the information given in the problem statement, is it possible to determine the sign of the charges? Explain.

(c) Find the tension in the string if +1.0 µC of charge is transferred from one point charge to the other. Compare with your result from part (a).
