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
