If energy (E), velocity (V) and time (T) are chosen as the fundamental quantities, the dimensional formula of surface tension will be:
[E V-2 T-2]
[E-2 V-1 T-3]
[E V-2 T-1]
[E V-1 T2]
As we learned in concept
To find the unit of physical quantity in a given system -
- wherein
P = Momentum
M=Mass
V = velocity
Surface Tension =
Surface Tension =
Option 1)

this is correct option
Option 2)
[E-2 V-1 T-3]
this is incorrect option
Option 3)
[E V-2 T-1]
this is incorrect option
Option 4)
[E V-1 T2]
this is incorrect option
