A) Tension and surface tension
B) Stress and pressure
C) Plancks constant and angular momentum
D) Angle and strain
Correct Answer: A
Solution :
Dimensions of surface tension are Surface tension \[{{f}_{0}}\] Tension \[{{f}_{e}}\]. Hence, dimensions of surface tension and tension are not equal. While dimensions of stress and pressure are \[Magnifying\text{ }power\propto \frac{1}{focal\,length\,ofeye-piece}\]. Plancks constant and angular momentum have dimensions \[{{f}_{e}}=+15cm\]. Also angle and strain are dimensionless quantities.
