Problem $8$: $(13\%$ of Assignment Value$)$

These graphs show the electric field magnitude outside a uniformly charged plane $($membrane$)$ as a function of distance away from the plane. Both curves represent measurements of electric field magnitude in an ionic solution, and both represent the same concentration of ions, but they are at different temperatures.

Part $($a$)$

Which of the following are true statements?

The higher curve represents a solution at higher temperature.

We can't determine anything about temperature from this graph. Temperature has no effect on electric field, so there must be some other factor causing the two curves to be different.

The lower curve represents a solution at higher temperature.

None of these.
