Question

2. A solid weighs 5ON in air and 44N
when completely immersed in water
calculate
;) the upthurst
ii) the volume of the solid
1.) the R.D of the solid​

Answer 1

Upthrust = Weight in Air - Weight in Water

Upthrust = Weight in Air - Weight in Water = 50 - 44 = 6 N

Buoyant Force = Density of Water × Acceleration due to gravity × Volume of solid

6 = 1000 kg/m^3 × 10 m/s^2 × Volume of Solid

Volume of Solid = 0.0006 m^3 = 600 cm^3

$relative \: density \: = \frac{wt. \: in \: air}{wt. \: in \: air - wt. \: in \: water}$

$= \frac{50}{50 - 44} = \frac{25}{3} = 8.34 \:$

Therefore, these are your answers.

I hope it helps you. If you have any doubts, then don't hesitate to ask.
