A spherical Gaussian surface encloses a point charge q. If the point charge is moved from the center of the sphere to a point away from the center, then

A Related Actual Mating Envelope (RAME) requires which of the following?

An electric dipole consists of point charges q1 = +6.00 nC and q2 = -6.00 nC placed 10 cm apart. Compute the electric potential at point a.

A capacitor is made from two hollow, coaxial, iron cylinders, one inside the other. The inner cylinder has radius 0.50 mm, the outer cylinder has radius 5.00 mm, and length of each cylinder is 18.0 cm. What is the capacitance? (1 pF = 10-12 F)

A charged comb can pick up uncharged pieces of plastic because:

What is the magnitude of the electric field required to store 100 J of electric potential energy in a volume of 1.00 m3 in vacuum?

A solid conducting sphere with radius R has net charge q. You put this sphere into a uniform electric field E which is to the right. The electric field inside the sphere is

A proton moves a distance d = 0.50 m in a straight line between points a and b in a linear accelerator. The electric field is uniform along this line, with magnitude E = 1.5×107 V/m in the direction from a to b. The potential difference Va – Vb is

Two irregular objects A and B carry charges of opposite sign. Figure shows the electric field lines near each of these objects. We can conclude
