Answer:
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 .
