Question

Pressure does not depend on area of contact. true or false

Answer 1

Answer:

False

Explanation:

Pressure=force/area

Pressure is indirectly proportionate to area as the more the area in contact the less pressure will be applyed whereas the less in area in contact the more the pressure would be applied.

for eg:-When we cut an apple we use the sharp egde of the knife. Blunt edge has more surface area and that's why less pressure is applied whereas the sharp edge has less area and that's why pressure applied is more and due to that it becomes easy to cut

Hope it is clear.If not you can ask in my inbox i can give more examples

Answer 2

False, the pressure depends upon the area of contact.

• Pressure is indirectly proportional to the area of contact.
• Greater is the area in contact lesser is the pressure.
• Pressure is force per unit area.
• Pressure = Force/ area
• The straps of the school bags are made wide so that a greater area in contact reduces the pressure on the shoulders.
• A drawing pin is made thin and sharp at its end so that a lesser area must be in contact and more pressure will help to insert the pin in the drawing board.
