Type: Assertion Reason-assertion-Hard-Class 11
Assertion (A): The work done by gravitational force on the Moon due to the Earth is zero. | Reason (R): The Earth's gravitational force on the Moon is perpendicular to the Moon's instantaneous displacement during its orbit.
A
Both A and R are true and R is the correct explanation of A.
B
Both A and R are true but R is not the correct explanation of A.
C
A is true but R is false.
D
A is false.
