Answer 1

Explanation:

as we know,

$p = f \div a - - - - - - (1)$

p=pressure

f=force

a=area

now,

$f = m \times g - - - - - (2)$

m=mass

g=acc. due to gravity

for first body,

by equ.(2)

$f = 10 \times 10$

$f = 100N$

by equ. (1)

area=(2*2)/(100*100)m^2

$p = 250000pascal$

for second body,

by equ (2)

$f = 5 \times 10$

$f = 50N$

by equ. (1)

area=0.5*1=0.5m^2

$p = 50 \div 0.5$

$p = 100pascal$

so,

pressure on body 1 =

$2.5 \times 10 ^{5} pascal$

pressure on body 2=

$1 \times 10 ^{2} pascal$
