Answer 1

Explanation:

Answer:-

In case of Figure A and B,

• The work is being done perpendicular against the gravity. And we know that when work is done perpendicular to gravity, then zero work is done.

For Example:-

We also need to know that work done in circular motion is zero.

So, work done by electron to orbit around a proton is also zero.
