AIIMS2009PhysicsUnits and Dimensions
The dimensions of specific resistance are
Options
- A[ M L ^2 ~T ⁻² ~A ⁻¹ ]
- B[ M L ^3 ~T ⁻³ ~A ⁻² ]
- C[ M L ^3 ~T ⁻² ~A ⁻¹ ]
- D[ M L ^2 ~T ⁻² ~A ⁻² ]
Correct answer
B. [ M L ^3 ~T ⁻³ ~A ⁻² ]
Step-by-step solution
Specific resistance = R A l aligned & = [ ML ^2 ~T ⁻³ ~A ⁻² ][ L ] & = [ ML ^3 ~T ⁻³ ~A ⁻² ] aligned
