Dimensional formula for activity of radioactive substance is
- A \(\left[M^0 L^1 T^{-1}\right]\)
- B \(\left[\mathrm{M}^0 \mathrm{~L}^{-1} \mathrm{~T}^0\right]\)
- C \(\left[\mathrm{M}^0 \mathrm{~L}^0 \mathrm{~T}^{-1}\right]\)
- D \(\left[\mathrm{M}^{-1} \mathrm{~L}^0 \mathrm{~T}^0\right]\)
Answer & Solution
Correct Answer
(C) \(\left[\mathrm{M}^0 \mathrm{~L}^0 \mathrm{~T}^{-1}\right]\)
Step-by-step Solution
Detailed explanation
Since, activity is defined as the number of disintegration per second.
Hence, its dimensional formula is \(\left[\mathrm{M}^0 \mathrm{~L}^0 \mathrm{~T}^{-1}\right]\).
Hence, its dimensional formula is \(\left[\mathrm{M}^0 \mathrm{~L}^0 \mathrm{~T}^{-1}\right]\).
