Question

2. The base areas of the 6 kg and the 4 kg blocks in
the given figures are in the ratio 4 : 1. The pressure
exerted on the ground in case A is
6 kg
4 kg
4 kg
6 kg
Case A Case B
(1) Four times of that in case B
(2) Twice of that in case B
(3) One fourth of that in case B
(4) Same as that in case B

Answer 1

one fourth of that in case B

Answer 2

Answer:

One fourth of B

Explanation:

If we take area of 6kg base block as 4x and base area of 4kg block as x

and force as y

then

pressure=force/area

               = y/4x

pressure = y/x

y/4x is 1/4th of y/x
