medium
The graph between terminal velocity (along $y-axis$ ) and square of radius (along $x-axis$ ) of spherical body of density $\rho $ allowed to fall through a fluid of density $\rho $ is $a$
A
Straight line with positive slope
B
Straight line with negative slope
C
Straight line perpendicular to $x-axis$
D
Straight line perpendicular to $y-axis$
Solution
$6\pi \sigma rv = \frac{4}{3}\pi {r^3}\rho $
