A) \[{{r}_{\alpha }}={{r}_{d}}>{{r}_{p}}\]
B) \[{{r}_{\alpha }}={{r}_{d}}={{r}_{p}}\]
C) \[{{r}_{\alpha }}<{{r}_{d}}<{{r}_{p}}\]
D) \[{{r}_{\alpha }}={{r}_{p}}>{{r}_{d}}\]
E) \[{{r}_{\alpha }}>{{r}_{d}}>{{r}_{p}}\]
Correct Answer: A
Solution :
In this case \[R=\frac{mv}{qB}=\frac{\sqrt{2KE.m}}{qB}\] Here \[R\propto \frac{\sqrt{m}}{q}=1:\sqrt{2}:1\] So, \[{{r}_{\alpha }}={{r}_{d}}>{{r}_{p}}\]You need to login to perform this action.
