A) decrease by a factor 2/3
B) decrease by a factor 4/9
C) decrease by a factor 5/9
D) decrease by a factor\[\sqrt{5}/9\]
E) increase by a factor 2/3
Correct Answer: C
Solution :
Since, \[E=\Delta m{{c}^{2}}\Rightarrow E\propto {{c}^{2}}\] \[\therefore \]\[\frac{E-E}{E}=1-{{\left( \frac{2}{3} \right)}^{2}}=\frac{5}{9}\]You need to login to perform this action.
