355801 A body of mass \(m\) \(kg\) is ascending on a smooth inclined plane of inclination \(\sin \theta \left( { = \frac{1}{x}} \right)\) with constant acceleration of \(a\). The final velocity of the body is \(v\). The work done by the external force is (Initial velocity of the body \(=0\) )

1 \(\dfrac{m v^{2}}{2}\left(\dfrac{g}{2}+a\right)\)
2 \(\dfrac{1}{2} m v^{2}(g+x a)\)
3 \(\dfrac{m v^{2}}{2 a x}(g+x a)\)
4 \(\dfrac{2 m v^{2} x}{2}(a+g x)\)
