Work Energy And Power Question 62
Question: If $ W_1,W_2 $ and $ W_3 $ represent the work done in moving a particle from A to B along three different paths 1, 2 and 3 respectively (as shown) in the gravitational field of a point mass m, find the correct relation between $ W_1,W_2 $ and $ W_3 $ [IIT-JEE Screening 2003]
Options:
A) $ W_1\gt W_2\gt W_3 $
B) $ W_1=W_2=W_3 $
C) $ W_1\lt W_2\lt W_3 $
D) $ W_2\gt W_1\gt W_3 $
Show Answer
Answer:
Correct Answer: B
Solution:
Gravitational force is a conservative force and work done against it is a point function i.e. does not depend on the path.
