1. The problem statement, all variables and given/known data A force, F=(6i-2j)[N], moves a particle through a distance deltaR=(3i+1j)[m] A. Find the work done on the particle B. Find the angle between F and deltaR 2. Relevant equations W=F*D 3. The attempt at a solution A. F=Root(6^2+2^2)=6.32N R=Root(3^2+1^2)=3.16m W=FD=(6.32*3.16)=20.00N/M I can't figure out B though. By the way, is my A correct? Thanks!
