If energy E, velocity V and time T are t...

If energy E, velocity V and time T are taken as fundamental units, the dimensional formula for surface tension is

Text Solution

Verified by Experts

The correct Answer is:
`[S]=Ev^(-2)T^(-2)`
Surface tension (S)
`=("work done")/("Area")=("Energy")/("Area")=[E/A]=[E/L^(2)]`
`:' L=vT :. S=E/((vT)^(2))=Ev^(-2) T^(-2)`
