If an electron and a proton having same ...

If an electron and a proton having same momenta enter perpendicular to a magnetic field, then

A

curved path of electron and proton will be same (ignoring the sense of revoluation)

B

they will move underclected

C

curved path of electron is more curved than thatt of the proton

D

path of proton is more curved

Text Solution

Verified by Experts

The correct Answer is:
2
Since electron and proton have same momenta so,the same force will act on them by the magnetic field
`F =qvB sin theta`
` =qvB ( :' theta =90^(@))`
Hence, both will move on same trajectory (curved path) .
