Two ions have equal masses but one is singly- ionized and the other is doubly- ionized. They are pojected from the same place in a uniform magnetic field with the same velocity perpendicular to the field.

Options

A. Both ions will go along circles of equal radii
B. The circle described by the single-ionized charge will have a radius tripply that of the other circle
C. the two circle do not touch each other
D. the two circle touch each other

Answer

B,D

Explanation

`R=(mv)/(qB)`
More `q` means less `R`
`(R_(1)/R_(2))=(q_(2)/q_(1))`
