PhysicsMediummultiple choice

A proton and an $α$ particle is projected in same magnetic field normally with same speed. Choose the correct option(s). (where 'R' is radius of circular path and 'T' is the time period of revolution)

Options:(select one or more)

Answer:

B, C

Solution:

$R = \frac{m v}{qB}$ and $T = \frac{2 πm}{qB}$

For proton (m, q) vs $α$ (4m, 2q): $\frac{R _{α}}{R _{p}} = 2$ and $\frac{T _{α}}{T _{p}} = 2$
