  The minimum energy needed to break carbon  of 12.000 amu into three  is α particles           (mass of  α particle = 4.0038 amu)

a
10.6 Mev
b
1.06 Mev
c
5.36 Mev
d
0.106 Mev

detailed solution

Correct option is A

mass defect 3mα -mC=( 3 x4.0038 -12) amu =0.0114 amu  energy equivalent 935 x 0.0114 Mev =10.6 MeV
