A solid weighs 0.09N in air and0.02N in a liquid of density 700kg/m³.Calculate the Upthrust of liquid on the solid and volume of the solid

Explanation:

solid weighs in air = .09 N .

solid weighs in liquid = .02 N

solid weighs less due to upthrust acting on it upwards .

upthrust = .09 - .02 = .07 N

upthrust = weight of liquid displaced

so weight of liquid equal to volume of solid = .07 N

mass of liquid equal to volume of solid = .07 / 9.8 = .00714 = 7.14 x 10⁻³ kg

volume = mass / density

volume of solid = 7.14 x 10⁻³ / 700

= 1.02 x 10⁻⁵ kg

= 1.02 x 10⁻² g .
