A force F = `(4.0 x hat(i) + 3.0 y hat(j))` N acts on a particle which moves in the x-direction from the origin to x = 5.0 m. Find the work done on the object by the force.

Explanation

Here the work done is only due to x component of force because displacement is along x-axis.
i.e., ` W = int_(x_(1))^(x_(2)) F_(x)"dx" = int_(0)^(5) 4x "dx" = [ 2x^(2)]_(0)^(5) = 50 J`
