NTA Abhyas JEE Main2020PhysicsUnits and DimensionsPractice
If L , C and R denote the inductance, capacitance and resistance respectively, the dimensional formula for C 2 L R is
Options
- A[ ML − 2 T − 1 I 0 ]
- BM 0 L 0 T 3
- C[ M − 1 L − 2 T 6 I 2 ]
- D[ M 0 L 0 T 2 I 0 ]
Correct answer
B. M 0 L 0 T 3
Step-by-step solution
C 2 L R = C 2 L 2 × R L As L R and L C both have the dimensions of time, we get C 2 L R = M 0 L 0 T 4 × M 0 L 0 T - 1 = M 0 L 0 T 3
