Vedclass · Answer

(C) The work done $(W)$ is defined by the formula $W = F \cdot s \cdot \cos(	heta)$,where $F$ is the force,$s$ is the displacement,and $	heta$ is the angle between the force and the displacement.In the case of the earth moving around the sun,the gravitational force acts towards the center of the sun (centripetal force),while the displacement of the earth is along the tangent to its circular orbit.Since the force and the displacement are perpendicular to each other,the angle $	heta = 90^\circ$.Therefore,$W = F \cdot s \cdot \cos(90^\circ) = F \cdot s \cdot 0 = 0$.Thus,the work done by the earth in moving around the sun is zero.
