Answer:
Explanation:
When a body is moving in a liquid, it experiences a backward dragging force. this backward dragging force is given by the formula
F = 6 π η r v
where, η is called the coefficient of viscosity, r be the radius, v be the velocity of object.
As we know that the coefficient of friction for oil is more than water so the dragging force in oil is more than water.
So, the balls in water comes first.
