As we know that, surface tension(s) is:

1. Force/F
2. Length/L
3. [MLT⁻²]/[L] = [MT⁻²]
4. Energy, (E) = Force × Displacement, [E] = [ML²T⁻²]

Correct answer: [MLT⁻²]/[L] = [MT⁻²]

Solution

Surface tension is defined as force per unit length, and its dimensional formula is derived as [MLT⁻²]/[L] = [MT⁻²].
