Two metal plates of area 2 xx10^(-4) m^(2)each, are kept in water and one plate is moved over the other with a certain velocity. The distance between the plates is 2 xx 10^(-4) m. If the horizontal force applied to move the plate is 10^(-3)N, calculate the velocity of the plate. Given etaof water is 10^(-3) decapoise.

1.	Two metal plates of area 2 xx10^(-4) m^(2)each, are kept in water and one plate is moved over the other with a certain velocity. The distance between the plates is 2 xx 10^(-4) m. If the horizontal force applied to move the plate is 10^(-3)N, calculate the velocity of the plate. Given etaof water is 10^(-3) decapoise.
Answer» Solution :` dv= FDX //eta A = 10 ^(-3)XX 2 xx 10 ^(-4) //10 ^(-3)xx 2 xx 10 ^(-4)= 1 m//s `
