a. Two 700-kg masses (1543 lb) are separated by a distance of 33 m. Using Newton’s law of gravitation, find the magnitude of the gravitational force exerted by one mass on the other. (Use G = 6.67 × 10-11 N·m2/kg2.) (Round the final answer to four decimal places.)

The magnitude of the gravitational force exerted by one mass on the other is ___________ × 10–9 N.

b. Two masses are attracted by a gravitational force of 0.36 N. What will the force of attraction be if the distance between the two masses is halved? (Round the final answer to four decimal places.)

The force of attraction will be _______ N.
