Question

Two particles of charge q and -q are projected from same point with a velocity v

Answer 1

Answer:

Two particle 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 θ with the magnetic field. Their masses are M and 2M respectively.

Answer 2

Answer:

In y direction:

h=ut+21gt2

So, t=g2h

In x direction

R=v×t

Now, In y direction

2h=uT+21gT2

T=gh

So, comparing range:

v×2h/g=v1×h/g

v1=√v2
