Two drops of the same radius are falling through air with a steady velcoity of `5 cm s^(-1).` If the two drops coalesce, the terminal velocity would be

A

10 cm per sec

B

2.5 cm per sec

C

`5xx(4)^(1//3)` cm per sec

D

`5xx sqrt2` cm per sec

Text Solution

Verified by Experts

The correct Answer is:

C

`implies v_2=5xx(4)^(1/3)` cm /s
