Question

15. A brick is kept in three different ways as shown in the figure. The
pressure exerted by the brick on the table will be *
A
B
C
O Maximum at position A
O
Maximum at position B
O Maximum at position C
Equal in all cases​

Answer 1

Answer:

The smaller the area, larger the pressure on a surface for the same force. Hence, the brick A whose area of contact is minimum will exert more pressure on the table.

Answer 2

Answer:

When we apply a brick A force, the pressure exerted by the brick is more on the table because the area is minimum. Still, in the case of B, when we apply pressure on brick B, it exerts less pressure as comparative to A because the surface area of brick is more; at last, when we applied force on brick C, it exerts very- very less pressure as comparative both A and B brick because the surface area of brick C increases double.

Therefore, the pressure exerted by the brick on the table maximum at position A.
