Consider the following nuclear decay: (initially `.^(236)U_(92)` is at rest)
`._(92)^(236)rarr._(90)^(232)ThrarrX`
Following atomic masses and conversion factor are provided
`._(92)^(236)U=236.045 562 u`,
`._(90)^(232)Th=232.038054 u`,
`._(0)^(1)n=1.008665 ,. _(1)^(1)p=1.007277 u`,
`._(2)^(4)He=4.002603 u` and
`1 u=1.5xx10^(-10)J`
The amount of energy released in this decay is equal to:

A

`3.5xx10^(-8)J`

B

`4.6 xx10^(-12)J`

C

`6.0xx10^(-10)J`

D

`7.4xx10^(-13)J`

Text Solution

Verified by Experts

The correct Answer is:
D
`Q=(m_(u)-m_(Th)-m_(x)).C^(2)`
`=(236.045562-232.038054-4.002603)xx1.5xx10^(-10)J`
`7.4xx10^(-13)J`.
