Question

Consider electron(e), proton (p), neutron(n), alpha(a) particles.

a moves towards positive charge
b travels undeflected
c and d both move towards negative charge
but d is more attracted to negative charge than c.

a,b,c,d are respectively are
A) e,p,n, a
C)e,n,a,p
B)p,n,a,e
D) e,n,p,a

the answer given is Option (C)
please explain​

Answer 1

Electron is negatively charged , So it was attracted by the positive charge in a magnetic field.

Neutron is electrically neutral, it has no charge , So it remains un deflected.

Proton and alpha particles ( double ionised helium ion) are positive charged ions

So, they are deflected towards negative charge.

As helium ion can accept electrons to form helium atom but not proton ,so it is more attracted to negative charge than alpha particles.

Thank you! and is waiting for more physics questions.
