QNEET-2022-Ph-537: NEET 2022 Physics - Class 12 NEET-2022-Ph-537 Solution: Given below are two statements Statement I: The law of…
Given below are two statements Statement I: The law of radioactive decay states that the number of nuclei undergoing the decay per unit time is inversely proportional to the total number of nuclei in the sample. Statement II: The half of a radionuclide is the sum of the life time of all nuclei divided by the initial concentration of the nuclei at time t = 0. In the light of the above statements choose the most appropriate answer from the options given below
Multiple Choice Options
- A Statement I is incorrect but statement II is correct
- B Both statement I and statement II are correct
- C Both statement I and statement II are incorrect
- D Statement I is correct but statement II is incorrect
Step-by-Step Verified Solution
According to law of radioactive decay
Rate of decay ( _ d N d t ) _ N (No. of undecayed nuclei)
Half life is the time in which half of the radioactive sample decays
_ Both statements are incorrect.
