[jenna1]

A charge Q is uniformly distributed along the x axis from x = a to x = b. If Q = 45 nC, a = -3.0 m, and b = 2.0 m, what is the electric potential (relative to zero at infinity) at the point, x = 8.0 m, on the x axis?
 a. 71 V
  b. 60 V
  c. 49 V
  d. 82 V
  e. 150 V

Question 2

A charge per unit length given by l(x) = bx, where b = 12 nC/m2, is distributed along the x axis from x = +9.0 cm to x = +16 cm. If the electric potential at infinity is taken to be zero, what is the electric potential at the point P on the y axis at y = 12 cm?
 a. 5.4 V
  b. 7.2 V
  c. 9.0 V
  d. 9.9 V
  e. 16 V
