How much energy is produced, if $2 kg$ of a substance is fully converted into energy? $[c = 3 \times 1 0^{8} ms^{- 1}]$

Options:

Answer:

Solution:

By Einstein's equation $E = mc^{2}$ where $m = 2 kg \Rightarrow E = 2 \times (3 \times 1 0^{8})^{2} = 2 \times 3 \times 3 \times 1 0^{16} = 18 \times 1 0^{16} J$
