A proton (mass m) accelerated by a potential difference V flies through a uniform transverse magnetic field B. The field occupies a region of space by width 'd'. If alpha ' be the angle of deviation of proton from initial direction of motion (see figure), the value of sin a will be:

Answer»

`qVsqrt( (pd )/(2m))`
`BD sqrt((q)/( 2MV))`
`(B)/(d )sqrt((q)/(2mV))`
