Question

A solid weighs 0.9N in air and 0.2N in a liquid of density 700kg/m^3. Calculate

Answer 1

The correct answer is Upthrust= 0.7N and Volume = 1.02 x 10⁻² g

Solid weighs.09 N in air.

Solid weighs less than liquid because of an upward force operating on it (solid weighs in liquid =.02 N).

A solid body experiences an upthrust when it is partially or entirely submerged in a fluid, such as water. In this case, the fluid's weight (water) equals the fluid's weight that the water has displaced.

upthrust is = to.09 -.02 N = 0.7N.

Upthrust = displaced liquid's weight

so that weight of liquid equal to volume of solid = 0.7 N

Volume of solid times mass of liquid = 0.07/9.8 = 0.00714 =  7.14 x 10⁻³ kg

Volume = Mass / density

Volume = 7.14 x 10⁻³ / 700

= 1.02 x 10⁻⁵ kg= 1.02 x 10⁻² g
