An atom bomb weighing 1 kg explodes relesing `9xx10^(13)` J of energy. What percentage of mass is converted into energy ?

A

`0.1%`

B

`1%`

C

`2%`

D

`10%`

Text Solution

Verified by Experts

The correct Answer is:
A
From `E=(Deltam)C^(2)`
`Deltam=(E)/(c^(2))=(9xx10^(-3))/((3xx10^(8))^(2))=10^(-3)kg`
`:. (Deltam)/(m)xx100=(10^-3)/(1)=0.1%`
