A small metal sphere of mass 5.7 g and charge 8.3 μC is fired with an initial speed of 1.7 m/s directly toward the center of a second metal sphere carrying charge 8.1 μC. This second sphere is held fixed. If the spheres are initially a large distance apart, how close do they get to each other? Treat the spheres as point charges.
Homework Answers
Concept - initially the spheres are large distance apart. Hence the potential energy will be zero. Thus the initial energy will consist only of the kinetic energy of the first sphere . Final energy will consist of only the potential energy because the sphere stops at the closest approach. Initial energy and final energy will be equal as per conservation of energy principle
