 Homework Statement:
 3 dimensional vectors
 Relevant Equations:

I have been given a question as follows :
A force 𝐹=2𝑖 +3𝑗 +𝑘 N moves a particle from 𝑟1=𝑖+2𝑗 m to 𝑟2=2𝑖 +4𝑗−𝑘 m.
Find the component of 𝐹 in the direction of the displacement. Give your answer to 3.s.f
I know the direction of the displacement is: i+2jk, but I do not know how to resolve in 3 dimensions. If anyone knows how to do this could they please help me. Thank you.
