an ionised gas contains both positive and negative ions. if it is subjected simultaneously to an electric field along the +x-direction and a magnetic field along the +z-direction, then what is the deflection of positive ions and negative ions????

positive ions get deflected in (+x),(-y) direction negative ions get deflected in (-x),(+y) direction

A paradox is an argument that starts with apparently acceptable assumptions and leads by apparently valid deductions to an apparent contradiction. Since logic admits no contradictions, either the apparently acceptable assumptions are not acceptable, or the apparently valid
deductions are not valid, or the apparent contradiction is not a contradiction. A paradox moves us to reexamine the argument until we find out what is wrong.

Its (-y)axis. . . .for both positive n negative charges,when they m0ve in same electric field(i.e. Along +X) Current is also al0ng +x and magnetic field is same fo both(i.e.+z) so both wil experienc forc in same directn,use FBI Gun(fleming's left hand) to get -y as th directn. . . . .i hope im n0t wr0ng ?
