Q239
Dimensions of surface tension are
A.
ML0T2
B.
ML0T-2
AnswerC.
ML1T-2
D.
ML-1T-2
Answer: Option B
Solution
Answer: Option B
Solution:
We know that Surface Tension (σ) = Force / Length Step-by-Step Dimensional Analysis:
1. Dimensional Formula of Force (F):
- Force = Mass × Acceleration
- Acceleration = Length / Time² = LT-2
- So, Force = M × LT-2 = MLT-2
2. Dimensional Formula of Length (L):
- L = L1
3. Dividing Force by Length:
- σ = (MLT-2) / L
- σ = ML(1-1)T-2 = ML0T-2
Thus, the correct dimensional formula for surface tension is ML0T-2, making Option B the correct choice.
