1.	Two identical charged particles enter a uniform magnetic field with same speed but at angles `30^(@)` and `60^(@)` with field Let a,b and c be the ratio of their time periods, radii and pitches of the helical paths than .A. `abc =1`B. `abcgt1`C. `abc lt 1`D. `a =bc`
Answer» Correct Answer - A,D `r =T = (2 pim)/(qB) a =1` `r =(mV_(1))/(qB), b = (sin 30^(@))/(sin 60^(@)) = (1)/(sqrt3)` Pitch a `v cos0 c = (cos 30^(@))/(cos 60^(@)` `So abc =1` .
