Question

A sinker is found to weigh 56.7 gf in water. when the sinker is tied to a cork of weight 6 gf, the combination is found to weigh 40.5 gf in water. Calculate the R. D.of cork

Answer 1

A sinker is found to weigh 56.7 gf in water. when the sinker is tied to a cork of weight 6 gf, the combination is found to weigh 40.5 gf in water. Calculate the R. D.of cork

Found two equation :

Now,

Weight of cork in air - Weight of cork in water

= 62.7 - 40.5

= 22.29

R.D of cork = Weight of cork in air / weight of cork in air - weight of cork water .
