Question

If a metal sphere of radius 1cm is charged with a "D" cell battery, a charge of 1.7 x 10^12C is developed. If this sphere is then placed in a cubic box with edges of length 30.0cm. What is the electric flux out of the box? Two particles with positive charge +Q and +2Q are evenly spaced about the origin on the y axis. About what plane(s) is the system symmetric? Select One of the Following: The system is not symmetric about any plane. The system is symmetric about the x - z plane. The system is symmetric about the y - z plane. The system is symmetric about the x - z and the y - z plane.

Explanation / Answer

problem 6.9

flux = charge/epsilon0=1.7*10^(-12)/8.854*10^(-12)=0.192

e is correct
