Question

The energy obtained when 1 mg mass is
completely annihilated is
(a) 9 × 10¹³ MeV (b) 9 × 10¹⁰ J
(c) 9 × 10¹³ J (d) 9 × 10¹⁶J

Answer 1

Answer:

d option id the correct answer

Answer 2

Answer:

Energy, E = 9 × 10¹⁰ joule

Explanation:

We have to find the amount of energy given in the conversion of 1 milligram of matter.

Using Einstein's mass- energy equivalence.

E=mc^2

E=10^{-6}\ kg\times (3\times 10^8)^2

E=9\times 10^{10}\ J

One milligram of matter convert into energy will give 9 × 10¹⁰ joule.

Hence, this is the required solution
