Q11 of 21 Page 16

How do you increase the pressure by keeping (a) area unchanged and (b) force unchanged?

Pressure is the ratio of force divided by area precisely the force counted is perpendicular to the area of consideration and not at any angle other than 90˚.



As we know that to increase the value of fraction we must increase the value of numerator or decrease the value of denominator.


a) To increase the pressure by keeping area constant or unchanged we must increase the force perpendicular to the area.


b) To increase the pressure by keeping force constant or unchanged we must decrease the area of application.

Karthik is observing the live telecast of a one day cricket match. He noticed motion of a roller on the pitch during lunch break. He thought about various forces acting on the roller and the net force when it is in motion. Many questions arose in his mind regarding the direction of the net force. Can you guess what would be those questions?
