Homework Statement
Consider two point charges placed on a line:
q1=1.00uc_______<2m>_________P_______<2m>________q2=-1.00uc
q1=1.00uc
q2=-1.00uc
r=2m
a) Find the electric field E at the position P *hint: bring + at P. Ep=Ep1+Ep2
b) Using the above E, find the electric force on the charge q=-1.00uc placed at P.
c) Check your answer F of (b) by computing directly F.
Homework Equations
(kq1/r12^2)
The Attempt at a Solution
I attempted to solve and with the charge acting on q1, I got 2.25X10^3 N/C. For the charge acting on q2, I received the answer -2.25X10^3 N/C. I figure this isn't correct since I need to use something other than 0 when these are added to figure out part b. Thanks for your help in advance!
