If B is added to C=5.1i^+2.9j^, 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 ? Number Units For the following three vectors, what is 3C(2AB) ? A=3.00i^+3.00j^3.00k^B=4.00i^+3.00j^+2.00k^C=7.00i^7.00j^ Number Units In the cross (or vector) product F=qvB we know that q=1F=51i^+21j^+60k^v=6.0i^+6.0j^+3.0k^B=Bxi^+Byj^+Bzk^ What then is B in unit-vector notation if Bx=By
