A body constrained to move in y-direction, is subjected

A body constrained to move in y-direction, is subjected to a force given by F^{^→} = (-2î + 15ĵ + 6k̂) N. What is the work done by this force in moving the body through a distance of 10m along y-axis ?

Since displacement is along the y-direction, hence displacement s^{^→} = 10ĵ .
Work done = F^{^→} . s^{^→}
= (-2î + 15ĵ + 6k̂) . 10ĵ = 150 J
