Electric field due to a line of charge: HELP!
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?
E = k * (q/(r^2))
dq = lamda * dx
replace q with dq
