The space between two large horizontal metal plates, `6 cm` apart, is filled with a liquid of viscosity `0.8 N//m^(2)` . A thin plate of surface area `0.01 m^(2)` is moved parallel to the length of the plate such that the plate is at a distance of `2 m` from one of the plates and `4 cm` from the other. If the plate moves with a constant speed of `1 ms^(-1)`, then

Options

A. The layer of the fluid, which has the maximum velocity, is laying mid-way between the plates
B. The two layers of the fluid, which are in contact with the moving plate on both sides are moving with maximum velocity
C. The layer of the fluid, which is in contact with the moving plate and is on the side of farther plate, is moving with the maximum velocity
D. The layer of the fluid, which is in contact with the moving plate and is on the side of nearer plate, is moving with the maximum velocity

Answer

B

Explanation

Velocity of water layer will be maximum near the moving plate.
