In both the cases work is not done. This is so because student does not apply any mechanical force and no displacement is done. And in case B although displacement and force are there but they are at an angle of 90 degrees. This is because radius of the orbit is mutually perpendicular to the tangent along which the earth is moving.

It isn't rotating tangentially. It's rotating in a circular pattern. Neither it is perpendicular to anything

But sir I am not talking about it’s movement what I am talking about is its velocity
You may check its answers from other sources...and let me know if I am wrong
And we are talking about revolution...not rotation
