Question

Select the correct statements among the following.

• A. The decay of mass during nuclear fusion and nuclear fission are $0.1$% and $0.231$% respectively
• B. Lesser is the half life, more dangerous is the radioactive element
• C. $K$-electron capture emits $\gamma$-rays
• D. Nuclear forces are about ${10}^{21}$ times stronger than coulombic forces

Answer 1

Answer: (A), (B), (D)

The decay of mass during nuclear fusion and nuclear fission are $0.1$% and $0.231$% respectively
Lesser is the half life, more dangerous is the radioactive element
Nuclear forces are about ${10}^{21}$ times stronger than coulombic forces

$-$The decay of mass during nuclear fusion and nuclear fission are 0.1% and 0.231% respectively.

$-$Lesser is the half-life, more dangerous is the radioactive element as it will have a very high activity.

$-$Nuclear forces are about ${10}^{21}$ times stronger than coulombic forces.

$-$$p+e^{-}\to n+v_e$.

K-capture does not emit $\gamma$-rays. It emits electron neutrino.
