The dimensions of k in the equation F = - k x (where F is force and x is displacement)
Find the dimensions of the following quantities: (i) the surfaces tension S, (ii) the coefficient of viscosity η.
Some equations involving these quantities are
S=ρgrh2 and F=−ηAv2−v1x2−x1
Where the symbol have their usual meanings.
ρ is density g is acceleration r, h and x are length
F is force, A is area.
