Question

The pair of quantities having same dimensions are Tension and surface tension Pressure and power Angular momentum and planck’s constant Force and impulse

Answer 1

Answer:

Angular Momentum and Planck's Constant

Explanation:

We know that E=hν

where dimensions of Energy, E are ML2 T−2

and dimensions of frequency are inverse of Time Period, i.e. T−1

 Thus, ML2 T−2  =[h]T−1

 or, [h]=ML2 T-1

 

Now, angular momentum, L=Iω

where units of omega are inverse of time (rad/sec, where radian is dimensionless).

Units of I are ML2  

Thus [L]=ML2T−1
