The amount of air present in a cylinder when a vacuum pump removes 1/4 of the air remaining in the cylinder at a time.
Answers
Let the volume of air in a cylinder, initially, be V litres.
In each stroke, the vacuum pump removes 1/4th of air remaining in the cylinder at a time. Or we can say, after every stroke, 1-1/4 = 3/4th part of air will remain.
Therefore:
- Volumes will be V, 3V/4 , (3V/4)² , (3V/4)³…and so on
Clearly, We can see here, the adjacent terms of this series do not have the common difference between them. Therefore, this series is not an A.P.
