The masses of `"^11C` and `"^11B` are respectively 11.0114 u and 11.0093 u.Find the maximum energy a position can have in the `beta^+`-decay of `"^11C` to `"^11B`.

Answer

C

Explanation

` `^(11) C rarr ^(11)B + (beta^+) + v`
Mass of ``C^(11) = 11.01u `
` massB^(11) = 11.0093 u `
` Energy libery = (11.014-11.0093)u`
` = 29.5127 MeV `
for maximum K E of the positron energy of a may be assarred as 0. ,
Maximum K. E. of the positron is 29.5127 MeV .
