In the formula V = E b d a , if V; E and dare the velocity of longitudinal waves, bulk modulus of elasticity and density of the gaseous medium respectively, then the values of a and b are respectively –
A
and 
B
and 
C
and 
D
and 
Text Solution
Verified by ExpertsThe correct answer is:
A
[V] = [E b d a ]
[LT –1 ] = [(ML –1 T –2 ) b (ML –3 ) a ]
equating power of M, L and T
0 = b + a, 1 = – b – 3 a
– 1 = –2b, ⇒ b = 
, a = –
