36. A charge per unit length given by 1(x) = bx, where b = 12 nC/m2, is distributed along the x axis from
x= t9.0 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
