Question

Consider a velocity selector shown below consisting of two parallel plates of opposite charge between which there is a uniform electric field of size 10^6 N/C in the direction shown. What should be the size and direction of t he magnetic field if charged particles with a speed of 10^7 m/s, moving to the right across the page, enter the region between the plates and are not deflected. Would charged particles with a speed greater than 10^7m/s moving to the right across the page be deflected upward or downward

Explanation / Answer

A) magnetic force = electric force

q*v*B = q*E

B = E/v = 10^6/10^7 = 0.1 T out of the page

B) if it was travelling with a speed greater than 10^7 m/s,then B becomes weaker,So E dominates

So it deflectes upwards
