`O^(++), C^(+), He^(++)` and `H^(+)` ions are projected on the photographic plate with same velocity in a spectrograph. Which one will strike farthest?

A

`O^(++)`

B

`C^(+)`

C

`He^(++)`

D

`H_(2)^(+)`

Text Solution

Verified by Experts

The correct Answer is:
B
`2r = (2mv)/(qB) rArr 2r prop (m)/(q) rArr (m)/(q)` is maximum for `C^(+)`
