[QUOTE="TSny, post: 6865959, member: 229090"] As a vector equation, you could write ##\mathbf{r}_2 = \mathbf{x} + \mathbf{r}_1##, where ##\mathbf{x}## is the vector from ##q_2## to ##q_1##. So, $$r_2 = |\mathbf{x} + \mathbf{r}_1| = \sqrt{x^2 + r_1^2 + 2xr_1\sin\theta_1}$$ I'm not able to read your handwriting too well. In your diagram it looks like you are using the symbol ##\theta_2## for the angle of ##\mathbf{r}_1## and ##\theta_1## for the angle of ##\mathbf{r}_2##. It could just be my poor eyes not reading your subscripts on the angles very well .:oldsmile: Otherwise, Your expression for the total E field looks good to me. The B field expression also looks good except I believe you dropped a factor of the speed ##v## in the numerators on the right side. Of course, I don't know if this form of writing the results is what is expected by the person who made up the problem. [/QUOTE]
