Two tiny metal spheres A and B of mass mA = 3.50 g and mB = 3.90 g have equal positive charges q = 4.50 µC. The spheres are connected by a massless nonconducting string of length d = 1.00 m, a distance that is much greater than the radii of the spheres.

(a) What is the electric potential energy of the system?

.18225J

(b) Suppose you cut the string. At that instant, what is the magnitude of the acceleration of each sphere?

52.1m/s2 (Sphere A)

46.7m/s2 (Sphere B)

(c) A long time after you cut the string, what is the speed of each sphere?

_________m/s (Sphere A)

__________m/s (Sphere B)

Two identical 7.10-g metal spheres (small enough to be treated as particles) are hung from separate 600-mm strings attached to the same nail in a ceiling. Surplus electrons are added to each sphere, and then the spheres are brought in contact with each other and released. Their equilibrium position is such that each string makes a 11.0 degree angle with the vertical. Part A: How many surplus electrons are on each sphere?
