Section 22.7 Challenge - Symmetry

Explanation 22.7.1. Flux Practice.

(a)

Choose an area vector for the loop.

(b)

Suppose a point charge $+Q_o$ is located at point $A\text{.}$ Is the electric flux through the loop positive, negative, or zero?

(c)

Suppose a point charge $+Q_o$ is located at point $A$ and a point charge $+2Q_o$ is located at point $B\text{.}$ Is the electric flux through the loop positive, negative, or zero?

(d)

Suppose a point charge $+Q_o$ is located at point $A$ and a point charge $-2Q_o$ is located at point $B\text{.}$ Is the electric flux through the loop positive, negative, or zero?

Explanation 22.7.2. Flux.

(a)

Is the electric flux through the right face of the cube positive, negative, or zero?

(b)

Suppose the charge on the right were replaced by a charge of $-q\text{.}$ Would the net electric flux through the entire cube increase, decrease, or stay the same?
