well, i found the electric field to be...
E= (2KQ)/(Lr) but they want me to solve for Q not for E so...
Q= (ERL)/(2K) --------> Q=(36x10^3)(.19m)(2.40m) / (2)(9x10^9)
Q=9.12x10^-7
i did this but could you double check. i checked in the back of the book, answer is correct but i am...
I am stuck on this one. I apprciate your help greatly.
A cyllindrical shape of radius 7cm and length 240 cm has its charge uniformly distributed on its curved surface.The magnitude of the electric field at a point 19cm radially outward from its axis (measure from the mid point of the shell)...
