Question

The pressure exerted by the brick on the table will be maximum in the position: [0.5 marks]

(a) A
(b) B
(c) C
(d) All positions will exert equal pressure.

Answer 1

Option (a) A (0.5 marks)

Pressure is given by the ratio of force (acting perpendicular to the area) to the surface area on which the force acts.
In the given situation, force is the same as the weight of the brick and is the same for all situations.
From the diagram, clearly surface area in contact is minimum in position A. Hence, pressure exerted would be maximum in position A.
