The relative velocity of two parallel layers of water is 8 cm/sec. If the perpendicular distance between the layers is 0.1 cm, then velocity gradient will be

A

60/s

B

50/s

C

40/s

D

80/s

Text Solution

Verified by Experts

The correct Answer is:
C
Velocity gradient=`(dv)/(dy)("in cm/s")/("in cm")`
`=8/(0.1)=80` per/sec
