Consider a spongy block of mass
floating on a flowing river. The maximum mass of the block is related to the speed of the river flow
, acceleration due to gravity
and the density of the block
such that
(
is constant). The values of
and
should then respectively be(Mass of the spongy block is assumed to vary due to absorption of water by it)
Text Solution
Verified by ExpertsThe correct answer is:
B
Maximum mass 
Using 

Put the dimensional formula on both side, we get,

Comparing the dimensions of
and
on both sides, we get

Solving eqn. (i), (ii) and (iii) we get the value of
and
.
