A body, constrained to move in the $Y-$direction is subjected to a force given by $\overrightarrow F = ( - 2\hat i + 15\hat j + 6\hat k)\,N.$ What is the work done by this force in moving the body a distance $10\, m$ along the $Y-$axis ...... $J$

$W = \vec F.\vec r$
$ = ( - 2\hat i + 15\hat j + 6\hat k)(10\hat j) = 150$
