Consider an insulating (non-conducting) sphere with radius b. It has a charge +Q uniformly distributed over its volume. What is the magnitude and direction of the electric field at a distance a from the center of the sphere if a > b? Question ID 3659985

A cube of side length L = [L] cm sits in a uniform electric field of magnitude E = [E] N/C in the x-y plane and is directed at an angle of [theta] degrees counter-clockwise with respect to the positive x-axis. What is the electric flux (in units of N

Two parallel plate capacitors are shown below. Capacitor on the left has capacitance C = Q/V, area A, and plate separation d. Capacitor on the right has the same capacitance and area. If the voltage is held constant and the plates are separated by a factor d’=2d, what is the new charge on the plates, Q’, after the separation?

Of the three scenarios listed below, determine which has the greatest magnitude of current through the source and calculate that value.   A. a [R1]-Ω resistor connected to a 2.0-V battery that has an internal resistance of 0.10 Ω.  B. an unknown resistor connected to a 12.0-V battery that has an internal resistance of [r2] Ω and a terminal voltage of 10.0 V. C. a [R3]-Ω resistor connected to a 4.0-V battery that has a terminal voltage of 3.4 V but an unknown internal resistance. Express your answer in units of A and to 2 decimal places. Numerical answer only. Don’t type in the units or use scientific notation.

Negative charge -Q is distributed uniformly along the x-axis between x=-d and x=+d. Which integral would give you the x-component of the electric field at point P with the correct sign (positive or negative)?  Question ID 3652774
