The time period of oscillation T of a small drop of liquid under surface tension depends upon the density rho, the radius r and surface tension sigma. Using dimensional analysis show that T prop sqrt((rhor^(3))/(sigma)) |
| Answer» Solution :`T=krho^(x)R^(y)sigma^(Z),[T]=[ML^(-3)]^(x)[L^(y)][MT^(-2)]^(z)`. SIMPLIFYING `x=1//2,y=3//2, z=-1//2`. | |
