A particle having charge q enters in a region of uniform magnetic field (directed inward) and get deflected by x after traveling a distance y. The magnitude of momentum of the particle is–
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
C
R = 
... (1)
mv = qBR .. (2)
(R – x) 2 + y 2 = R 2 (Pythagoras) .. (3)
R 2 + x 2 – 2xR + y 2 = R 2 ... (4)
R = 
From (2) and (4) mv = qB 
P =
