B. Two objects with different charge are separated by a distance of 2 meters. The first object
exerts a force on the second of 64 N. The distance between them is increased such that the
force of the second on the first becomes 4 N. What is their final separation?
(a) 8 m (b) 16 m (c) 32 m (d) 512 m
(e) Their individual charges must be known to determine this
