268643 A lawn roller is pulled along a horizontal surface through a distance of \(20 \mathrm{~m}\) by a rope with a force of \(200 \mathrm{~N}\). If the rope makes an angle of \(60^{\circ}\) with the vertical while pulling, the amount of work done by pulling force is

268698 If a force \(\vec{F}=(\vec{i}+2 \vec{j}+\vec{k}) \mathbf{N}\) acts on a body produces a displacement of \(\vec{S}=(4 \vec{i}+\vec{j}+7 \vec{k}) \mathbf{m}\), then the work done is

268699 Work done by the gravitational force on a body of mass " \(m\) " moving on a smooth horizontal surface through a distance ' \(s\) ' is

268700 A body of mass \(1 \mathrm{~kg}\) is made to travel with a uniform acceleration of \(30 \mathrm{~cm} / \mathrm{s}^{2}\) over a distance of \(2 \mathrm{~m}\), then work to be done is
