1. The problem statement, all variables and given/known data The picture below shows two stationary charges q1= +2mC and q2= -15 mC. and I need to find the electric field vector at field point P(0,4m). E= [px, py] . Also A little dipole is positions in P(0,4m) and is given with p= [px,py]=[2*10^-8 ,0] Cm. Find the torque that acts on the dipole because of the electric field and its potential energy 2. Relevant equations E=k*q/r^2 3. The attempt at a solution I have found out that E1=4.5*10[/SUP] and E2= 1.7*10^6. I am not sure if the electric field E1 is negative or positive ? I think its negative because the vector goes downwards. And when I find the angle for E2 do I use arctan(8/2)?
