1. The problem statement, all variables and given/known data If B is added to C = 3.0î + 4.0ĵ, the result is a vector in the positive direction of the y axis, with a magnitude equal to that of C. What is the magnitude of B? 2. Relevant equations a = sqrt(ax2 + ay2) 3. The attempt at a solution 1. Found the magnitude of C c = sqrt(cx2 + cy2) = sqrt(32 + 42) = 5 2. Added B to C and got this equation 5 = sqrt(ax2 + ay2) = sqrt(b2 + 52) which obviously isn't right because I get the magnitude of B as 0. I'm not sure what I am doing wrong, but any guidance would be helpful. Thank you.
