Question

Which will exert more pressure: a 100 kg mass on the area of 100 cm2 or a 50 kg mass on 25 cm2?

Answer 1

Answer:

50 kg object experience more pressure.

Explanation:

Since pressure is defined as the ratio of force and area.

$P =\dfrac{Force}{Area}$

For 100 kg and 100 cm^2

Since weight (W) is the kind of force so, weight of 100 kg = 100 x 9.8 = 980 N

$P= \dfrac{W}{A}$

$P = \dfrac{980}{100} = 9.8 N/m^{2}$

For 50 kg and 25 cm^2

Weight of 50 kg = 50 x 9.8 = 490 N

$P= \dfrac{W}{A}$

$P = \dfrac{490}{25} = 19.6 N/m^{2}$

So,50 kg object experience more pressure.
