Multiple Choice

A charge of 10 nC is distributed uniformly along the x axis from x = -2 m to x = +3 m.Which of the following integrals is correct for the electric potential (relative to zero at infinity) at the point x = +5 m on the x axis?

A) $\int _ { - 2 } ^ { 3 } \frac { 90 d x } { x }$
B) $\int _ { - 2 } ^ { 3 } \frac { 90 d x } { 5 - x }$
C) $\int _ { - 2 } ^ { 3 } \frac { 18 d x } { x }$
D) $\int _ { - 2 } ^ { 3 } \frac { 18 d x } { 5 - x }$
E) $\int _ { - 2 } ^ { 3 } \frac { 90 d x } { 5 + x }$
