Two tiny conducting spheres are identical and carry charges of -18.8 µc and +46.5 µc. they are separated by a distance of 2.47 cm. (a) what is the magnitude of the force that each sphere experiences, and is the force attractive or repulsive? n

, attractive.

Explanation:

For calculating this force we use the Coulomb Law:

Where is the Coulomb's constant, and the values of each charge and r the distance between them.

Since the Coulomb's constant as I wrote it is in S.I. we have to write all the magnitudes in that system of units, and substitute:

This force is attractive since both charges are of opposite sign.
