Given that K = energy, V = velocity, T = time. If they are chosen as the fundamental units, then what is dimensional formula for surface tension?

Question

TestHub · Accepted Answer

Surface tension = ℓ F ​ = ℓ F ​ ⋅ ℓ ℓ ​ ⋅ T 2 T 2 ​ (As, F . ℓ = K ( energy) ; ℓ 2 T 2 ​ = V − 2 ) Therefore, surface tension = [ K V − 2 T − 2 ]
