Previous Year Questions of KCET Nuclei
The candidates can refer to some previous year's questions asked from the Nuclei chapter. Check some of the questions here.
- A radioactive sample has a half-life of 3 years. The time required for the activity of the sample to reduce to 1/5th of its initial value is about
- 10 years
- 7 years
- 15 years
- 5 years
Correct Answer: B
- A nucleus with mass number 220 initially at rest emits an alpha particle. If the Q value of the reaction is 5.5 MeV. Calculate the value of the kinetic energy of the alpha particle
- 6.5 MeV
- 5.4 MeV
- 7.4 MeV
- 4.5 MeV
Correct Answer: B
- In a nuclear reactor, heavy nuclei are not used as moderators because
- They will break up
- Elastic collision of neutrons with heavy nuclei will not slow them down
- The net weight of the reactor would be unbearably high
- Substances with heavy nuclei do not occur in liquid or gaseous state at room temperature
Correct Answer: B
- A radioactive element has a half-life of 15 years. What is the fraction that will decay in 30 years?
- 0.25
- 0.5
- 0.75
- 0.85
Correct Answer: C
