Dimensional formula for activity of radioactive substance is
Options
- A[M^0 L^1 T⁻¹ ]
- B[ M ^0 ~L ⁻¹ ~T ^0 ]
- C[ M ^0 ~L ^0 ~T ⁻¹ ]
- D[ M ⁻¹ ~L ^0 ~T ^0 ]
Correct answer
C. [ M ^0 ~L ^0 ~T ⁻¹ ]
Step-by-step solution
Since, activity is defined as the number of disintegration per second. Hence, its dimensional formula is [ M ^0 ~L ^0 ~T ⁻¹ ] .
