20N.1A.HL.TZ0.32

The graph shows the variation of electric field strength $E$ with distance $r$ from a point charge.

The shaded area X is the area under the graph between two separations $r_{1}$ and $r_{2}$ from the charge.

What is X?

A. The electric field average between $r_{1}$ and $r_{2}$

B. The electric potential difference between $r_{1}$ and $r_{2}$

C. The work done in moving a charge from $r_{1}$ to $r_{2}$

D. The work done in moving a charge from $r_{2}$ to $r_{1}$
