charged particule reaches a uniform magnetic B field with a velocity V , and at angle theta with the magnetic field .
What is the expression of the relation , expressed as a ratio, of the radius and helical step of the trajectory of the particule .
a- 2pi/tan a
b- 2pi tan a
c- 2pi tan a
d- tan a / 2pi
p = (v cos theta 2 pi m) / qB
F= m * ( v^2 / r )
period = 2pim / qB
ffrquency and angular frequency
qB / 2pim qB / m
The Attempt at a Solution
after algebraic manipulations, i ended up with ( m tangent theta / 2 pi ) , so correct answer is D ?
