Answer:
Mass of ion will be [tex]22\times 10^{-13}kg[/tex]
Explanation:
We have given ion is triply charged that is [tex]q=3\times 1.6\times 10^{-19}=4.8\times 10^{-19}C[/tex]
Radius r = 36 cm = 0.36 m
Velocity of the electron [tex]v=7\times 10^6m/sec[/tex]
Magnetic field B = 0.55 T
We know that radius of the path is given by [tex]r=\frac{mv}{qB}[/tex]
[tex]m=\frac{rqB}{v}=\frac{0.36\times 4.8\times 10^{-19}\times 7\times 10^6}{0.55}=22\times 10^{-13}kg[/tex]
