Magnetic field applied on a cyclotron is...

Magnetic field applied on a cyclotron is `0*7T` and radius of its dees is `1*8m`. What will be the energy of the emergent protons in `MeV`? Mass of proton`=1*67xx10^-27kg`.

Text Solution

Verified by Experts

The correct Answer is:
D
`E=(q^(2)B^(2)r^(2))/(2m)=((1.6xx10^(-19))^(2)xx(0.7)^(2)xx(1.8)^(2))/(2xx1.67xx10^(-27))`
`=1.22xx10^(-11)J="76 MeV"`
