સુક્ષ્મ સ્થાનાંતર \(dx\) માટે થતું કાર્ય  \(dW\,\, = \,\,\mathop F\limits^ \to  \,.\,\,\mathop {dx}\limits^ \to  \,\, = \,\,(10\,\, + \,\,0.5x)\,dx\) છે. 

થતું કુલ કાર્ય \({\text{W}}\,\, = \,\,\,\int\limits_{{\text{x}}\, = \,{\text{0}}}^{x\, = \,2} {{\text{(10}}\,\, + \,\,{\text{0}}{\text{.5x)}}\,{\text{dx}}\,\, = \,\,\left[ {{\text{10x}}\,\, + \,\,\frac{{{\text{0}}{\text{.5}}{{\text{x}}^{\text{2}}}}}{2}} \right]} _0^2\, = \,\,\,10(2\,\, - \,\,0)\,\, + \,\,\frac{{0.5}}{2}\,({2^2}\, - \,\,0)\,\, = \,\,21\)
