Question

Two particles are called to be equal settling, if they are having the same

• A. Size
• B. Specific gravity
• C. Terminal velocities in the same fluid \& in the same field of force
• D. Solubility

Hint:

Equal settling = same terminal velocity, used in classification and sedimentation.

Answer 1

The Correct Option is C

Equal settling particles fall at the same terminal velocity in a fluid under gravity.
They may differ in size or density but balance each other to achieve same settling velocity.
