Statement 1: |
Comets move around the sun in elliptical orbits. The gravitational force on the comet due to sun is not normal to the comet’s velocity but the work done by the gravitational force over every complete orbit of the comet is zero |
|
Statement 2: |
Gravitational force is a non conservative force |
|
a) |
Statement 1 is True, Statement 2 is True; Statement 2 is correct explanation for Statement 1 |
|
b) |
Statement 1 is True, Statement 2 is True; Statement 2 is not correct explanation for Statement 1 |
|
c) |
Statement 1 is True, Statement 2 is False |
|
d) |
Statement 1 is False, Statement 2 is True |
|
(c) The gravitational force on the comet due to the sun is a conservative force. Since the work done by a conservative force over a closed path is always zero (irrespective of the nature of path), the work done by the gravitational forces over every complete orbit of the comet is zero |
