A streamlined body falls through air from a height h on the surface of a liquid. If d and D (D > d) represents the densities of the material of the body and liquid respectively, then the time after which the body will be instantaneously at rest, is
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
D
Up thrust – weight of body = apparent weight
Where a = retardation of body ∴ ∴ 
The velocity gained after fall from h height in air, 
Hence, time to come in rest,
