A Spherical ball of radius 1mm 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 × 10–x N. The value of x is $\left(\right.$ Given, $g=9.8 \mathrm{~m} / \mathrm{s} 2$ and $\left.\pi=\frac{22}{7}\right)$
