1)Two small metallic spheres, each of mass m = 0.25 g, are suspended as pendulums by light strings from a common point as shown in the figure below. The spheres are given the same electric charge, and it is found that they come to equilibrium when each string is at an angle of ? = 8.9° with the vertical. If each string has a length L = 26.0 cm, what is the magnitude of the charge on each sphere? ______ nC

1)Two small metallic spheres, each of mass m = 0.25 g, are suspended as pendulums by light strings from a common point as shown in the figure below. The spheres are given the same electric charge, and it is found that they come to equilibrium when each string is at an angle of ? = 8.9° with the vertical. If each string has a length L = 26.0 cm, what is the magnitude of the charge on each sphere?

______ nC

 

2)Two metal balls A and B of negligible radius are floating at rest on Space Station Freedom between two metal bulkheads, connected by a taut nonconducting thread of length 2.35 m. Ball A carries charge q, and ball B carries charge 2q. Each ball is 2.00 m away from a bulkhead.

(a) If the tension in the string is 2.55 N, what is the magnitude of q? (Ignore any contribution from induced charge in the bulkheads.)
 
_____uC
 
(b) What happens to the system as time passes? Explain. (Assume the thread is oriented perpendicular to the bulkheads.)
