Question

Two charged particles M and N are projected with same velocity in a uniform magnetic field. The M and N are: M X M A. A proton and alpha -particle respectively B. A deuteron and an electron respectively C. An electron and a proton respectively D. A protium and a proton respectively​

Answer 1

Answer:

Answer would be A

Explanation:

The difflection in inversely proportional to mass.... Proton and electron have almost same masses but opposite charges so proton will deflect upward and electron downward and alpha particle also have positive charge like proton but have less mass then proton so it will deflect in the same way as proton but slightly away

Hope it will be helpfull

Answer 2

The correct option is "a"

Radius of charge particle in uniform magnetic filed  

r=  qB /mv

r∝  q m    _(1)

According to the given figure, Center of the both curve is same side, Hence nature of both side will be same.  

The deuteron is neutral so it don't gate deflection.

From equation 1

M have less radius so it will have less mass in compare to N.

Hence the answer is:

A proton and alpha -particle respectively
