Questions
A proton, a deuteron and an α particle whose kinetic energies are same enter at right angles to a uniform magnetic field. Then the ratio of the radii of their circular paths is
detailed solution
Correct option is A
Radius of circular path =r=2mKBq ⇒r ∝ mq ⇒rp : rD : rα = mpqp : mDqD : mαqα= 11 : 21 : 42= 1 : 2 : 1Talk to our academic expert!
