Question

a rock of mass of 540 g in the air is found to have an apparent mass of 342 g when submerged in water (a) calculate the weight of the Rock given that the acceleration of the air g 10 m / s² to ignore the air resistance​

Answer 1

Answer: 5.4 N

Step-by-step explanation:

Given

mass of rock in the air is 540 g

Apparent mass of 342 gm when submerged in water

Weight of the rock is the product of mass and accleration due to gravity

`\Rightarrow W=mg\\\Rightarrow 0.540* 10=5.4\ N`
