Question

the charge and mass ratio is the highest for :-
a. the proton
b. the electron
c. the Alpha particle
d. sodium positive

Answer 1

The right answer is the proton because Proton is 1840 times heavier than electron.

Answer 2

Answer:

THE ELECTRON

Explanation:

Electrons and protons have the same charge.(1.602×10^-19c)But protons are 1840 times heavier than electrons.E/M of any particle decreases if the mass is increased. So the E/M of electron is higher than the proton.

Alpha particle is a helium nucleus which consists two protons and two electrons. It has +2 charge and the mass of four protons. So the alpha particle has the least E/M because of its large mass.You can see that its E/M is equal to 1/2 time E/M of a proton.

Neutron has no charge. Then its E/M is 0.

If we arrange those particles in the order of increasing E/M we get,

Neutron,Alpha particles,protons and at last electrons.
