Two charged particles `P` and `Q` enter a uniform magnetic field normally with the same speed. Their paths in the field are as shown in the figure. It can be concluded that
(i) the charge of `P` is greater than of `Q`
(ii) specific charge of `P` is `gt` that of `Q`
(iii) both `P` and `Q` are positively charged
(iv) both `P` and `Q` are negatively charged

Options

A. (i), (ii)
B. (ii), (iv)
C. (ii), (iii)
D. (i), (iv)

Answer

B

Explanation

`R_(Q) gt R_(p)`
`((m)/(q))_(Q) gt ((m)/(q))_(P)`
`((Q)/(m))_(Q) lt ((q)/(m))_(P)`
`(q)/(m)`: specific charge
