F = k(q1q2/r^2)
The Attempt at a Solution
I know pretty much what to do for the problem, but I cannot get the right answer. I think my issue lies within what angles I am using for the components. Because it is an equilateral triangle, all angles within that triangle are 60 deg. But when I use 60 deg to calculate the components in the x & y directions, I can't come up with the right answer.
F of 2 on 1 = 0.0579 N
F of 3 on 1 = 0.0358 N
x: 0.0579 cos 60 -i, 0.0358 cos 60 +i
y: 0.0579 sin 60 -j, 0.0358 sin 60 -j
Sum these together and use Pythagoras for overall magnitude
The magnitude the above produces is 0.0818 N
I am not getting the right answer. Thus I think my problem lies in the angles I am using. Can anyone shed some light?
