Question

One milligram of matter converted into energy will give 

(A) 90 J 

(B) 9 × 10³ J 

(C) 9 × 10¹⁰ J 

(D) 9 × 10⁵ J

Answer 1

Correct option (C) 9 × 10¹⁰ J  

Explanation:

We know that, 1 kilogram of matter is equivalent to an energy = 9×10¹⁶ Joule 

1000 (10³) gram of matter is equivalent to an energy = 9×10¹⁶ Joule 

1000000 (10⁶) milligram of matter is equivalent to an energy = 9×10¹⁶ Joule 

1 milligram of matter is equivalent to an energy = 9×10¹⁰ Joule
