A Spherical ball of radius 1 mm and density 10.5 g/cc is dropped in glycerine of coefficient of viscosity 9.8 poise and density 1.5 g/cc. Viscous force on the ball when it attains constant velocity is $3696 \times 10^{-x}$ N. The value of x is (Given, $g = 9.8 m/s^2$ and $\pi = \frac{22}{7}$) - FirstInTest | FirstInTest
