(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

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.

2. Relevant equations

(kq1/r12^2)

3. 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!
