A) \[1.5\times {{10}^{-10}}J\]
B) \[3\times {{10}^{-10}}J\]
C) \[4.5\times {{10}^{-10}}J\]
D) \[6\times {{10}^{-10}}J\]
Correct Answer: B
Solution :
Mass of proton = mass of antiproton \[=1.67\times {{10}^{-27}}kg=1\] amu energy equivalent to \[1\text{ }amu=931\text{ }MeV\] so energy equivalent to \[2\text{ }amu=2\times 931\text{ }MeV\] \[=1862\times {{10}^{6}}\times 1.6\times {{10}^{-19}}\]joule \[=2.97\times {{10}^{-10}}\] joule \[=3\times {{10}^{-10}}\] jouleYou need to login to perform this action.
