Question

A small solid spherical ball of high density is dropped in a viscous liquid. Its journey in the liquid is best described in the following figure by the

• A. $CurveA$
• B. $CurveB$
• C. $CurveC$
• D. $CurveD$

Answer 1

The correct option is C $CurveC$

When a body is dropped in a liquid, at first, the dominating weight will lead to an increase in its velocity but at a certain velocity, the forces on it get balanced resulting in the body moving with constant velocity thereafter.
$F_v=6\pi \eta rv$

All these processes are subsequent as all forces are conservative there will not be any jerk in the journey so, the correct graph is shown by Curve C.
