Question

A solid weighs 0.040N in air and 0.024N when fully immersed in a liquid density 800kg. Calculate the volume of the solid (g=10mls)?

Answer 1

bouyant force= .04-.024=.016N

but that has to equal to the weight of the displaced liquid
.016=800kg/m^3l*g*volumedisplaced
volume displaced=.016/8000 m^3=2ml
