Question
The energy equivalent of 2.0 mg mass defect is
Options
A.1.8 × 104 erg
B.9 × 10-19 erg
C.1.5 × 1020 erg
D.1.8 × 1018 erg
Solution
Using the repletion, ᐃE = ᐃm × C3
(ᐃm in kg, ᐃE in J)
2mg = 2 × 10-6 kg
∴ ᐃE = 2 × 10-6 × (3 × 108)2J
= 2 × 10-6 × 9 × 1016J = 18 × 1010J
= 18 × 1010 × 107 erg
(ᐃm in kg, ᐃE in J)
2mg = 2 × 10-6 kg
∴ ᐃE = 2 × 10-6 × (3 × 108)2J
= 2 × 10-6 × 9 × 1016J = 18 × 1010J
= 18 × 1010 × 107 erg
