Question:

Two point charges, the first with a charge of +3.13 × 10-6 C and the second with a charge of -4.47 × 10-6 C, are separated by 25.5 cm.
(a) Find the magnitude of the electrostatic force experienced by the positive charge.
(b) Is the magnitude of the force experienced by the negative charge greater than, less than, or the same as that experienced by the positive charge? Explain.
