Question 379: Gravitation

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 (as shown in fig) in the gravitational field of the point mass ' $m$ '. Find the correct relation between ' $W_1$ ', ' $W_2$ ' and ' $W_3$ '

Accepted Answer

Gravitational force is a conservative frorce. As we know that the work done by a conservative force is independent of the path followed and depends only on the end points of the motion. Since in the given pattern $w_1, w_2$ and $w_3$ have the same end point $A$ and $B$ as shown in the figure below,
So, the correct relation between is $w_1=w_2=w_3$

Answer

$W_1< W_3< W_2$

Answer

$W_1< W_2< W_3$

Answer

$W_1=W_2=W_3$

Answer

$W_1>W_3>W_2$
