Questions
A charged particle of mass m and charge q enters along AB at point A in a uniform magnetic field existing in the rectangular region of size The particle leaves the region exactly at corner point C. What is the speed v of the particle ?
detailed solution
Correct option is A
Let speed of the particle be v (speed will remain constant).r=AO=CO=mvqB; Also ar = sin θ, r−br=cos θSolving the above equations, we get v=qBa2+b22mbTalk to our academic expert!
