Question

How much mass defect is required to release 5.5 x 1020 J of energy?

Answer 1

Answer : The mass defect required to release energy is 6111.111 kg

Explanation :

To calculate the mass defect for given energy released, we use Einstein's equation:

`E=\Delta mc^2`

E = Energy released =
`5.5* 10^(20)J`

`\Delta m` = mass change = ?

c = speed of light =
`3* 10^8m/s`

Now put all the given values in above equation, we get:

`5.5* 10^(20)Kgm^2/s^2=\Delta m* (3* 10^8m/s)^2`

`\Delta m=6111.111kg`

Therefore, the mass defect required to release energy is 6111.111 kg
