uestion 1 known charqg c a, and a range of possib l vclocities enicr a vegion of space with crossed clectr sC an moghetic Fields arranged as sShown as velocity se te ctor. 61 d 62 in this velocy Se te ctor, th iS E 171 Clo)NI S8 147 mT. and a plate Separation of ds1.5bcm,After energi ng from the ve locity sete ctor, the particie enters another region ith only a constant magnetic Fic ld 62 0mt directcd to the Page H will creatc a pth of radius 2.4m. Ic and the magnitude of the magnetic ficd The plates of the selector have a length LOm al what is the velocity of a Charged particle that can -emerge from the ve locity se lector undefected? in KmIs b) what is the chare of ParticleExplanation / Answer
(a) Velocity of particle which passes undeflected is given by:
V = E/B = 1710/0.147 m/s = 1.1632 x 104 m/s
(b) As particle moves anti-clockwise in the magnetic field which is directed towards the inside of the plane of the paper. Hence, this must be a Positively charged particle. (Because, gyration of the charge particle must produce magnetic field in a direction opposite to the applied magnetic field)
