The angle at which the particle enters the magnetic field is changed from 45 degrees to 60 degrees. How will the pitch of the path be affected? |
It will increase. It will decrease. It will become 3 times. Cannot be predicted. |
It will decrease. |
It will decrease. Pitch : p = 2πmv Cos θ/qB Cos 45 = 1/\(\sqrt {2 }\) = 0.71 Cos 60 = 1/2 = 0.5 |
