After terminal velocity is reached the acceleration of a body falling through a viscous fluid is :
Open in App
Solution
The correct option is C zero
One the terminal velocity is reached, both the forces balance each other, i.e.; weight is balanced by the viscous force and buoyancy.
Hence acceleration is zero.
