Alpha Scattering:


In the schematic diagram of the alpha scattering experiment, what is the final or terminal velocity of the alpha particle:

1)2*10^6m/s
2)10^6m/s
3)Finally the alpha particle comes to rest.
4)None of these

    should be 1),i guess..simply angular momentum conservation abt center of atom coz nuclear forces are assumed central..

    you're all right here..quite simple..

    yaar digvijay, my first argument is that you simply can't solve it if you assume all that!!

    your friction argument sounds good, but i can't say that its correct..

    STICKING=finite friction force acting at a pt with zero velocity??? maybe no work is done..but just maybe..

    also, this was a question of varying mass, but i REALLY don't want any of you to get into that.

    just enjoy the solution..if there was some ambiguity, such a one would NEVER feature in JEE...

    yaar, i did just one similar question during my JEE prepn.
    it will involve many equations(4-5), and the solution that i have, even i'm not sure of.

    i'll suggest you to leave it.
    the rotational dynamics questions asked in JEE are really simpler. the involvent of a number of equations is seldom encountered.
