In the experiment for measurement of viscosity '\(\eta\)' of given liquid with a ball having radius '\(R\)', consider following statements.
A. Graph between terminal velocity V and R will be a parabola.
B. The terminal velocities of different diameter balls are constant for a given liquid.
C. Measurement of terminal velocity is dependent on the temperature.
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 '\(\eta\)' will change.
Choose the correct answer from the options given below:
[JEE Main 2025, 28 Jan (Shift 1)]
A, C and D only
\(\sigma =\) Density of ball
\({V}_{T}=\frac{2{R}^{2}}{2\eta }(\sigma -\rho )g\\ {V}_{T}\propto {R}^{2}\)
As temperature changes Co-efficient of viscosity changes.
