Question

31. In a gravitational force field a particle is taken from A to B along different paths as shown in figure. Then a) Work done along path I will be maximum b) Work done along path III will be minimum c) Work done along path IV will be minimum (d) Work done along all the path will be the same​

Answer 1

Answer:

d is the answer for the question

Answer 2

Given:

In a gravitational force field a particle is taken from A to B along different paths as shown in figure.

Image is attached.

To find:

Correct option ?

Solution:

• Always remember that gravitational force is a conservative force and the work done against gravitational force depends on the position of the object with respect to the reference.

• So, the work done doesn't depend on the path taken by the object.

In this attached figure, we can see that the initial and final position are A and B , since the initial and final states for the particle is same for all the three paths (I , II , III) , we can say that :

Work done along all the paths are same.
