In the previous question, if the pitch of the helical path is equal to the maximum distance of the particle from the x-axis

Options

A. `cos theta=1/pi`
B. `sin theta=1/pi`
C. `tan theta=1/pi`
D. `tan theta=pi`

Answer

(a,b,c)

Explanation

Pitch `=((2pim)/(QB))v cos theta` and radius `r=(mv sin theta)/(QB)`
Maximum distance of the particle from the x-axis =2r
`:. ((2pim)/(QB))v cos theta =2(mv)/(QB)sin theta`
or `tan theta=pi`
Hence, the option (a) ,(b) and (c) are not correct.
