A) A physics instructor in an anteroom charges an electrostatic generator to 25uC, then carries it into the lecture hall. Find the net electric flux, in Nm^2/C, through the lecture hall walls.
B) A particle with charge is placed at the corner of a cube.Find the total electric flux, in Nm^2/C, through all sides of the cube.
C) A cylinder plastic (non-conducting) wastepaper basket, with a 0.15m radius opening, is in a uniform electric field of 300N/C, perpendicular to the opening. Find the total flux through the sides and bottom, in Nm^2/C.
