Question

In the present graph,the area of circle A and B are 25unit and 20 unit respectively work done will be 5x units.x=​

Answer 1

Answer:

Since Direction of arrow of both the cyclic work is opposite

Work done is=25-20=5 Unit

Answer 2

Work done will be 5x units, where x=1.

Given :

In the P-V graph, The area of Circle A is 25 units.

The area of circle B is 20 units.

To Find:

Value of x in work done of 5x units.

Solution:

Work done PV graph is the net area under the curve.

Here Circle A is in an anticlockwise direction and circle B is in the Clockwise direction.

The net area of circle A and circle B are = 25 - 20 = 5 units

The work done is 5x units.

5x= 5

⇒x= 1

Hence, x= 1.
