Question

In a nuclear reactor, the fuel is consumed at the rate of 1 mg/s. The power generated in kilowatt is-

• A. 9 × 10⁴
• B. 9×10⁷
• C. 9 × 10⁸
• D. 9 × 10¹²

Answer 1

Answer: (B)

9×10⁷

Answer 2

$\frac { \mathrm { m } } { \mathrm { t } }$= $1 \frac { \mathrm { mg } } { \mathrm { sec } }$ = 10^–6 $\frac { \mathrm { kg } } { \mathrm { sec } }$

E = mc²

Power = = = 10^–6 × (3×10⁸)²

P = 9 × 10¹⁰ W
