1. The problem statement, all variables and given/known data
Positive charge q = 7.81 X 10^-12 C is spread uniformly along a thing nonconducting rod of length L = 14.5 cm or .145 m. What are (a) magnitude and (b) direction (relative to the postive direction of the x axis) of the electric field produce at point P, at distance R = .06 m from the rod along its perpendicular bisector?


2. Relevant equations
E = k * (q/(r^2))

dq = lamda * dx

replace q with dq









3. The attempt at a solution

Use symmetry and integration to solve. Try drawing the line charge along the y axis, pick a point on the line charge, dq, and express dE at a point P along the x axis created by dq.
