Q1) two particles of charges +q and-q are
projected from the same point with a velocity v
in a region of uniform magnetic field B such
that the velocity vector makes an angle ‘theta’
with the magnetic field. Their masses are m
and 2m then they will meet again for the first
time at a point whose distance from the point
of projection is :
Q2) a particle of specific charge q/m is
projected from the origin of coordinates with
initial velocity u towards +x and v towards –y
Uniform electric and magnetic fields exist in
the region along +y of magnitude E & B
The particle will definitely return to the origin if
a) vB/2piE is an integer
b) vB/piE is an integer
c) (u^2 + v^2)^.5B/piE is an integer
d) uB/2piE is an integer
