Question

arrange the e\m value of the following in the increasing and decreasing order :
electron, proton ,neutronand
Alpha particle​

Answer 1

E/M value of any particles is inversely proportional to the mass of that particles.

So, alpha particles have more mass. Therefore it have least e/m value. Neutrons have no charge. so it have 0 e/m value.

Now if we arranged them in ascending order

=>Neutrons,alpha particles,protons and then electrons.

Hope it helps:)
