The working principle of the mass spectrograph is that for a given combination of accelerating potential and magnetic field. The radius of curvature of the ion beam of charge q and mass m collected at different positions on the collector will depend on the value of

Answer»

`sqrt((m)/(2q))`
`(m)/(q)`
`sqrt((m)/(q))`
`(m)/(2q)`

Solution :Let velocity with which charge enters magnetic FIELD is v
`:. (1)/(2) mv^(2) = qv_(0) rArr v= sqrt((2qv_(0))/(m))`
Charge is COLLECTED at 2r.
`:. 2r= 2(mv)/(qB)= (2m)/(qB) sqrt((2qv_(0))/(m))= sqrt((m)/(q)) ((2 sqrt2v_(0))/(B))`
