Question

HELP ME PLS FAST!!!! ​

Answer 1

Answer:

You should always remember the fact that work done is equal to the product of force applied and the displacement.

Now, the question wants us to assume that the trajectory of the Earth around the sun is a perfect circle.

So when the Earth is revolving,the displacement vector is always perpendicular to the force vector applied by the sun.

So work done = F * d* cos( theta)

Theta is 90° , cos (90°) = 0

Therefore work done is zero (0).

Hope you will be able to understand.
