Question

A pressure of 100 pa acts on a surface of area 15 cm2 by a block of mass claculate value of ' m'

Answer 1

P = 100 Pa

A = 15cm^2 = 0.0015m^2

M = ?

P = F / A

100 = F / 0.0015

100 * 0.0015 = F

F = 0.15 N

Now force exerted by the body is equal to its W.

F = M g

0.15 = M * 9.8

0.15 / 9.8 = M

M = 0.015 Kg
