Physics II

In figure two tiny conducting balls of identical mass m and identical charge q hang from nonconducting threads of length L. Assume that θ is so small that tan θ can be replaced by its approximate equal, sin θ. Find the magnitude of q in terms of the given variables, using ε0 and g if necessary.

If L = 170 cm, m = 11 g, and x = 4.2 cm,

Two identical cork balls, each of mass m, are hung from a common point by two insulating threads of negligible mass, each of length L = 50.0 cm. Each ball has a charge Q = - 0.2 C distributed uniformly over its volume. The balls repel each other and assume an equilibrium position as shown. ( 30° from the center line.) a) Draw a free-body force diagram for one of the two masses. b) Write down ∑Fx = max and...
