NTA Abhyas JEE Main2020PhysicsUnits and DimensionsPractice
The dimensional formula for areal velocity is
Options
- A[ M 0 L - 2 T ]
- B[ M 0 L - 2 T - 1 ]
- C[ M 0 L 2 T - 1 ]
- D[ M 0 L 2 T ]
Correct answer
C. [ M 0 L 2 T - 1 ]
Step-by-step solution
Areal velocity is the area covered per unit time. ∵   A r e a   = [ L 2 ] ∴ A r e a l   v e l o c i t y = [ L 2 T - 1 ]
