emi:
can some one explain for me for each of " alpha, gama, beta " radiations their

deflection in magnetic field
deflection in an electric field


thanks

deflections of rays in magnetic fields
alpha is positively charged so in magnetic field in to the paper (the north pole faced towards a paper) (uding flemings left hand u point ure index finger just like the way u would point at somone and with the thumb up and ure middle finger pointing towards the right(which is the direction alpha rays)) so doing this would indicate tht alpha rays deflects upwards.
however the beta rays(negatively charges) moves opposite to the deflection of alpha rays (i.e downwards but with the same conditions set as experssed for the alpha rays)
whereas in gamma rays, no deflection in magntic field.

deflections of rays in an electrical field.
lets say there are 2 charged plates place over another(with gap inbetwwen), one is postively charged plate which is for example the upper plate, and the lower plate is negatively charged. alpha rays deflect yowards the negative side (i.e downwards) as it is postively charged, whereas the beta rays deflects towards the positively charge plate(i.e upwards, just opposite of alpha rays). gamma rays do not deflect in electric fields either.

hope this helped, any confusion difficulties or help needed, plz do ask me

emi:
thanks shogun that was great help .
and i understood each word you said  =]

<33

Shogun:
ure welcome ;D
