Question

which will exert more pressure 100 kg mass on 10 m square or 50 kg mass on 4 m square give reason

Answer 1

Mass(1) = 100kg
Area (1) = 10m^2
Pressure (1) = 100/10 = 10Pa
Mass(2) = 50kg
Area(2) = 4m^2
Pressure(2) = 50/4 = 12.5 Pa
10Pa<12.5Pa
Thus in second case more pressure is exerted.
I hope I solved your problem mark me as brainly

Answer 2

pressure = mass /area
in case 1 , mass = 100kg ,area = 10 m square
so , pressure = 100/10 =10 Pascal
in case 2 , mass = 50 kg , area = 4 m square
so ,pressure = 50/4 =12.5 Pascal
therefore pressure exerted by 50 kg mass on 4 m square is more
since 12.5 Pascal is greater than 10 pascal
hope u understood the problem and even the reason
