a 2.0 kg particle is given a displacement (delta)r= 2.0i+3.0j (m). During this displacement, a constant force, F=2.0i5j (N) acts at the particle. find the work done by the force for this displacement.

drwls,
Work is the dot product of the Force and Displacement vectors.
I assume you know what a dot product is. If not, you need to review that subject.
