A small spherical ball of radius r, falling through a viscous medium of negligible density has terminal velocity ' v '. Another ball of the same mass but of radius 2r, falling through the same viscous medium will have terminal velocity:
A
B
C
4v
D
2v
Text Solution
Verified by ExpertsThe correct answer is:
A
Since density is negligible hence Buoyancy force will be negligible
At terminal velocity.
