Question

If power of nuclear reactor is $100$ watt then rate of nuclear fission is:-

• A. $3.6\times {10}^6$ per second
• B. $3.2\times {10}^{12}$ per second
• C. $1.8\times {10}^6$ per second
• D. $1.8\times {10}^{12}$ per second

Answer 1

The correct option is B $3.2\times {10}^{12}$ per second

$\begin{array}{c}\text{Given- * Power of nuclear reactor}=100\text{watt}\\ \text{we know that -}\\ \text{Rate of nuclear fission =}\frac{\text{Power}}{\text{energy}/\text{fission}}\end{array}$

$\begin{array}{cc}\text{Rate}& =\frac{100w}{200\times {10}^5\times 1.6\times {10}^{-19}w-s}\\ & =3.2\times {10}^{12}\text{per Sec.}\end{array}$
