If energy (E), velocity (v) and time (T) are fundamental units. What will be the dimension of surface tension?
Surface tension (S)=workdoneArea=EnergyArea=[EA]=[EL2]
∵L=vT∴S=E(vT)2=Ev−2T−2
If energy (E), velocity (V) and time (T) are chosen as the fundamental quantities, thendimensional formula of surface tension will be :
