Question
Calculate the energy released in joules when 5 g of a material is completely converted into energy doing a nuclear reaction.
Solution
The energy released in joules when 5 g (5/1000 kg ) of a material is completely converted into energy during a nuclear reaction is given by Einstein's equation as
E = mc2
= `(5/1000) xx (3 xx 10^8)^2`
= 4.5 × 1014 J
