1) The dimensional formula of coefficient of viscosity is A) [MLT-1]B) [M-1L2T-2]C) [ML-1T-1]D) None of these |
| Answer» 1 L-1 T-1 ]Explanation:Coefficient of viscosity (η)= Fr/Av where F = tangential force, R= distance between the layers , v= velocity.Dimensional Formula of Force =[M 1 L1 T -2]Dimensional Formula of Area=[M 0 L2 T 0]Dimensional Formula ofdistance= [M 0 L 1 T 0]Dimensional Formula of velocity=[M 0 L1 T -1]PUTTING these values in aboveequation we get,[η]= [M 1 L 1 T-2 ][M 0 L 1 T0 ] /[M 0 L2 T0 ] [M 0 L 1 T-1 ] =[M 1 L-1 T-1 ] | |
