Answer:
a) 1 / 3 N
b) 5/3 m/s
Explanation:
For constant speed V at the interface of the two fluids the net force is zero.
Hence, F top = F bottom thus the shear stresses at top and bottom must be the same.

For force of top plate

Answer:
2kg
Explanation:
Because the 2kg carries more weight, gravity will affect it more, meaning it will land on Earth's surface faster than the 1kg rock.
