The drag offered by liquid will be maximum in:
The drag offered by liquid will be maximum in:
Open in App
Solution
The correct option is D Q
When a body moves through a liquid, it experienes a frictional force by the liquid medium called as drag. The drag offered by the liquid medium depends on:
1. Nature of the liquid
2. Shape of the object
3. Speed of the object in the liquid
Here, the shape of the body in all cases is the same i.e spherical. Only the nature of the liquids and the speed of the body in the liquids are different.
Denser the liquid, more friction it applies. Friction offered by the liquid will be even more if the body moves with high velocity through the liquid.
Honey is more dense than water. In case Q, the body is moving through honey and its speed is highest as compared to the rest of the cases.
Hence, the friction offered by the liquid is maximum in case Q.
