Answer to Question #91006 in Physics for Zainab

Question

A solid weighs 0.040N in air and 0.024N when fully immersed in a liquid of density
800kgm. Calculate the
volume of the solid (g = 10ms2)
(a) 2.0 x 10-6m3 (b) 2.5 x 10-6m3 (c) 3.0 x10-6m3 (d) 2.0 x 10-6m3

Answer 1

$$W_a-W_l=\rho g V$$

The volume of the solid:

$$V=\frac{W_a-W_l}{\rho g}$$

$$V=\frac{0.04-0.024}{(800)(10)}= 2.0 \cdot 10^{-6}m^3$$
