Can someone please help me with the question that is attached as a JPEG to this post.
I have worked out:
F3 = -11.24 x 10 ^-6
F1 = 16.86 x 10^-6
I am now unsure of how to carry on with the rest of the quesiton.
To find the magnitude of q2 do I use the cosine rule?
And to find the direction do I use :
a/sina = b/sinb
Any help would be appreciated, thanks.
