a particle of massm, accelerated by a potential differece V flies through a uniform transverse magnetic field B. The magnetic field is spread in the thickness d. calculate the angle through which particle will deviate from the initial direction of motion.

 hi ,

 velocity of particle  v = ( 2*q*V/m) ^1/2

^{& radius of path , r = m*v /q*B}

^{if d > r} 

     ^{than particl will cover one half circle & will leave at 180  angle deviated from initial}

^{if  d= r}

      ^{than particl will cover one fourth of circle & will leave at 90  angle deviated from initial}

 ^{if   d < r}

^{than  it will deviat  an angle of  sin^ -1 (d/r)}
