Question

The work done in moving a particle under the effect of a conservative force from position to be A to B is 4 j and from B to C is 3 joule.the work done in moving the particle from A to C is

Answer 1

Explanation:

this will be the sum of both the work done I. e. 4+3=7joules

Answer 2

The work done in moving the particle from A to C is 7 Joules.

Explanation:

Given that,

The work done in moving a particle under the effect of a conservative force from position to be A to B is 4 J and from B to C is 3 joule. We need to find the work done in moving the particle from A to C. We know that if the force is conservation, than the work done in moving particle is independent of path covered.

So,

$W_{A,C}=W_{A,B}+W_{B,C}$

$W_{A,C}=4\ J+3\ J$

$W_{A,C}=7\ J$

So, the work done in moving the particle from A to C is 7 Joules. Hence, this is the required solution.
