Question

Conical block floats in water with 9% height immersed in it.height nof the of the block is equal to the dianneter of the block i. 20cm the mass to be kept on the block (a) 568g (b) 980g (c) 112g (a) sogg (b) 980g (c) 112g

Answer 1

Thus the mass kept on the block is 558 g.

Option (A) is correct.

Explanation:

h / h / 2 = 0.9 h / r

r = 0.9 h / 2

Upthrust:

= 1/3 πr^2 (0.9h) g ρ1

= 1/3 π ( h / 2)^2 h. g ρ

When totally submerged:

w + 1/3  π ( h / 2)^2 ghps

= 1/3 π ( h / 2)^2 gph

Thus the mass kept on the block is 558 g.
