Point charges q1 and q2 are placed in space, with q1 at the origin and q2 a distance r from q1 making a 45 degree angle with the horizontal.(adsbygoogle = window.adsbygoogle || []).push({});

a) Find the force using unit vectors i and j from q1 to q2

b) " " from q2 to q1

c) If q1=q2, what is the magnitude of the force?

so far i have:

q2:

Fx = F cos (theta)

Fy = F sin (theta) - so F(1on2) = F cos(theta)i+ F sin (theta)j

am I on the right track? and would F(2on1) be -F(1on2)?
