But use pressure=force/area
And if area is higher pressure is lower
Answer:
The correct answer is option (a). maximum in position A
Explanation:
From the above question,
They have given :
A brick is kept in three different ways on a table as shown in the figure giben. The pressure exerted by the brick on the table will be
(a) . maximum in position A
(b) . maximum in position C
(c) . maximum in position B
(d) . equal in all cases
The strain is inversely proportional to the place on which the pressure is being exerted. When a brick is saved on a desk in (A) position, the place of contact will be minimal and the strain exerted on the desk will be maximum.
In position A, the brick is standing upright on its smallest surface area. This means that the weight of the brick is distributed over a smaller area, resulting in a higher pressure exerted on the table.
In position B, the brick is lying on its longest surface area. This means that the weight of the brick is distributed over a larger area, resulting in a lower pressure exerted on the table.
In position C, the brick is lying on its smallest surface area. This is similar to position A, and the pressure exerted on the table will be relatively high.
Therefore, the answer to the question depends on the specific dimensions and weight of the brick in each position.
The correct answer is option (a). maximum in position A
