Suppose two bees, each with a charge of 93.0 pC, are separated by a distance of 1.20 cm. Treating the bees as point charges, what is the magnitude of the electrostatic force experienced by the bees? (In comparison, the weight of a 0.140-g bee is 1.37 × 10-3 N.)

A. 6.01 × 10-17 N

B. 6.48 × 10-9 N

C. 5.40 × 10-7 N

D. 5.81 × 10-3 N
