A body of density 
is counterpoised by 
of weights of density 
in air of density d. Then the true mass of the body is
A
M
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
D
Let 
mass of body in vacuum.
Apparent weight of the body in air = Apparent weight of standard weights in air
Actual weight – upthrust due to displaced air = Actual weight – upthrust due to displaced air
