Question
The energy produced by converting 1 gram mass of a nuclear fuel into energy completely is:
(a) 9 × 1016 J
(b) 9 × 1014 J
(c) 9 × 1015 J
(d) 9 × 1013 J
Solution
(d) 9 × 1013 J
The energy produced by converting 1 gram (1/1000 kg) mass of a nuclear fuel is given by Einstein's equation as
`E=mc^2`
`(1/1000)xx(3xx10^8)^2=9xx10^13j `
