l need detailed answer basicly solution manuel  answer is 38.01 

Consider a non-conducting rod of length 8.8 m having a uniform charge density 4.5 nC/m . Find the electric potential at P, a perpendicular distance 9.04 m above the midpoint of the rod.(Take Coulomb's constant 9x109Nm2C2).Write your answer in Nm/C unit. And write your answer in two decimal places. O 129.5 dx margin of error +/- 0.1 38.01
