The velocity of a small ball of mass 10 g and density `7.8 g//c c`. When dropped in a container filled with glycerine becomes constant after some time. If the density of glycerine is `1.3 g//c c`. What is the viscous force acting on the ball?

Explanation

To find the viscous force acting on the ball when it reaches its terminal velocity in glycerine, we can follow these steps:

### Step 1: Calculate the weight of the ball
The weight \( W \) of the ball can be calculated using the formula:
\[ W = m \cdot g \]
where:
