In the experiment for measurement of viscosity ' 
' of given liquid with a ball having radius
R, consider following statements.
A
Graph between terminal velocity V and R will be a parabola. A, B and E Only
B
The terminal velocities of different diameter balls are constant for a given liquid. B, D and E Only
C
Measurement of terminal velocity is dependent on the temperature. A, C and D Only
D
This experiment can be utilized to assess the density of a given liquid. (E) If balls are dropped with some initial speed, the value of 
will change. Choose the correct answer from the options given below: C, D and E Only
will change. Choose the correct answer from the options given below: C, D and E Only
Text Solution
Verified by ExpertsThe correct answer is:
C
The terminal velocity of ball of radius R inside a liquid of viscosity 
can be written as 
, where 
is the density of ball and 
is the density of the liquid.
Hence,
A is correct since 
gives a parabola on a graph
C is correct since 
and 
varies with temperature
D is correct since 
i.e., varies with density of liquid.
