An Intiative by Sri Chaitanya
a
The minimum coefficient of friction necessary for not sliding of the vessel due to the impact force of the emerging liquid is 32aA
b
Range of efflux is 3H2
c
If position of orifice is H2 from bottom then range of efflux is maximum which is Rmax=H
d
From option (c) , if a < < < A is not considered , then Rmax1>H
answer is A.
