An α particle is accelerated by a potential difference of 10 4 V. Find the change in its direction of motion, if it enters normally in a region of thickness 0.1 m having transverse magnetic induction of 0.1 Tesla. (Given: mass of α-particle is equal to 6.4 × 10 –27 kg)
Text Solution
Verified by ExpertsThe correct answer is:
B
r = 
& 
mv 2 = qV
= 
r = 
= 0.2
sin θ = 
= 
⇒ θ = 30
