The terminal velocity formula is: \ (V_ {Terminal} = \sqrt {2 g h}\) \ (= 197.98 m s^ {-1}.\) Thus terminal velocity will be \ (197.98 ms^ {-1}\) Q.2: Determine the height of the body if its terminal velocity is \ (100 m s^ {-1}\) Solution: Given parameters in the question are. Terminal velocity \ (V_ {terminal} = 100 m s^ {-1},\) The height ...
Solution. Verified by Toppr. The terminal velocity of an object is the maximum constant velocity acquired by the object while falling freely in a viscous medium. Terminal velocity (v) of an object of radius (r) density ( ρ) moving through a viscous medius of viscosity η and density ρ 0 is given by. v = 2 9 r 2 η ( ρ − ρ 0) g.
Solution. When a body falls in a viscous medium, it carries with its layers of fluid which are in body's contact where as the layers of fluid in contact with the stationary surface remain almost at rest. The layers of fluid destroys the relative motion and motion of the body is thus opposed. The viscous drag increases with velocity of the body ...

The terminal velocity of a liquid drop of radius r falling through air is v. If two such drops are combined to form a bigger drop, the terminal velocity with which the bigger drop falls through air is (Ignore any buoyant force due to air) : √ 2 v; 2 v; 3 √ 4 v; 3 √ 2 v
Terminal velocity is the maximum velocity attainable by an object as it falls through a fluid. It occurs when the sum of the drag force and the buoyancy is equal to the downward force of gravity acting on the object.
The terminal velocity of a steel ball 2 mm in diameter falling through glycerin is 44 × 10 − 2 c m / s (Given that specific gravity of steel = 8, specific gravity of steel =8, specific gravity of glycerin a 1.3, viscosity of glycerine 8.3 poise.)
A small spherical ball falling through a viscous medium of negligible density has terminal velocity v. Another ball of the same mass but of radius twice that of earlier falling through the same viscous medium will have terminal velocity
An oil drop falls through air with a terminal velocity of 5 × 10 − 4 m / s. Viscosity of oil is 1.8 × 10 − 5 N s / m 2 and density of oil is 900 k g / m 3. Neglecting density of air as compared to that of the oil, choose the correct statements.
Terminal velocity is the maximum velocity attained with constant value. For constant value of velocity, there must be no net force acting on object. In Air: Terminal velocity is obtained, when the net downward forse ( due to gravity) becomes equal to net upward force ( buoyancy, drag force).
