A fusion reaction consists of combining four protons into an `alpha`–particle. The mass of `alpha`–particle is 4.002603u and that of proton is 1.007825u, mass of electron is 0.00054466u.

A

the equation `4p_(1)^(1)toHe_(2)^(4)` does not satisfy conservation of charge

B

the correct reaction equation may be `4p_(1)^(1)toHe_(2)^(4)+2beta^(+)+2upsilon` where `beta^(+)` is positron and `upsilon` is the neutrino (zero rest mass and uncharged)

C

loss of mass in the reaction is 0.028697 u

D

the energy equivalent of the mass defect is 26.7 MeV

Text Solution

Verified by Experts

The correct Answer is:
A, B, C, D
Mass defect `Deltam=4m_(H)-m_(He)`
`=4(1.007825)-4.002603=0.028697u`
`=0.02897uxx932=26.7 MeV`
