Given the electric field E, angle 0, mass m, expression for the charge q. Charges q and -q are located at x = a and x = -a, respectively, Point P is located at y = b. Find an expression for the electric field at point P. What is the direction of this electric field? Use Gauss's Law to find an expression for the electric field inside a uniformly charged sphere of total charge Q and radius R. Explain what you are doing. Consider a 3.0 cm times 3.0 cm times 3.0 cm cube. a. What is the electric flux ohi_2 through side 2? b. What is the net flux through all four sides? A solid metal sphere is at the center of a hollow metal sphere E = 15,000 N/C, r_1 = 5.0 cm, r_2 = 8.0 cm, r_3 = 10.0 cm, and r_4 = 17.0 cm. Develop an expression for the surface charge density, eta, on the inside surface of the hollow sphere. Write a sentence or two on your reasoning to come up this expression

Explanation / Answer

The electric force on the mass m with charge q will be:

F(e) = q E

this is directed along x.

This electric force is balanced by the gravitational force, along x

F(g) = mg tan(theta)

F(e) = F(g)

q E = mg tan(theta)

q = [ mg tan(theta)] /E
