An aluminum sphere is dipped into water. Which of the following is true?
A
Buoyancy will be less in water at 
than that in water at 
than that in water at
B
Buoyancy will be more in water at 
than that in water at 
than that in water at
C
Buoyancy in water at 
will be same as that in water at 
will be same as that in water at
D
Buoyancy may be more or less in water at 
depending on the radius of the sphere
depending on the radius of the sphere
Text Solution
Verified by ExpertsThe correct answer is:
A
Let volume of the sphere is V and 
is its density, then we can write buoyant force 
( 
acceleration due to gravity)
( 
and g are almost constant)
Hence, buoyancy will be less in water at 
than that in water at 
.
