Answer:
the work done is 0.
Explanation:
we know that formula for work is,
W= F×S (where F is the force acting on the object and S is the displacement)
the force by which sun pulls the earth and the force by which earth pulls the sun are mutually perpendicular, i.e. 90°
when there i an angle included, the formula changes to,
W=F·Scos(theta)
=>F×Scos90°
=>F×S×0 (∵cos90°=0)
=> 0
