Question

an object moves with some speed inside a liquid with which of the following speed should it more so as to experience minimum drag?​

Answer 1

Answer:

The speed of the object moving through a fluid affects the amount of friction acting against the motion of the object. More the speed, more is the friction. If the object is broad, it gives more area for the friction to act on. Thus, a streamlined body structure helps to cut through the fluid and reduce friction.
