## Homework Statement

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

## Homework Equations

W=F*D

## 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!
