3 point charges are fixed in place in the right triangle shown below, in which q1= 0.67 microC and q2= -0.67 microC. What is the electric force on q3 with +1.0 microC due to the other two charges?
direction, measured counterclockwise from the +x axis?
**HYP=10cm or .1m (q1-q3)
**Opp=8cm or .08m (q1-q2)
[k (q1) (q1)]/d^2
The Attempt at a Solution
f13= (8.99e9 * .67e-6 * 1e-6)/ .1^2 <-- shouldn't this provide the magnitude from q1 & q2 on q3?
