Magnetic Effects Of Current Question 397
Question: A charged particle moves insides a pipe which is bent as shown in fig. If $ R>\frac{mv}{qB} $ , then force exerted by the pipe on charged particle at P is (Neglect gravity)
Options:
A) toward center
B) away from center
C) zero
D) none of these
Show Answer
Answer:
Correct Answer: A
Solution:
[a] Radius of circular path of the charged particles $ r=\frac{mV}{qB} $ Here R < r, hence the particle will press the outer wall of the pipe hence the force applied by the pipe on the particle should be towards the centre of the pipe.
