Protons having kinetic energy K emerge f...

Protons having kinetic energy K emerge from an accelerator as a narrow beam. The beam is bent by a perpendicular magnetic field so that it just misses a plane target kept at a distance I in front of the accelerator. Find the magnetic field.

Redius `= 1 KE = K`
since `l = mu/qB `
`rArr l = (sqrt 2km)/ (qB)`
` `B = (sqrt 2Km ) /(ql) `

A stream of protons and deuterons in a vacuum chamber enters a uniform magnetic field. Both protons and deuterons have been subjected to same accelerating potential, hence the kinetic energies of the particles are the same.
