According to Newton's second law, we can write
r=mvBq(1)r=\frac{mv} {Bq} (1)r=Bqmv(1)
The speed is equal to
v=2EKm(2)v=\sqrt {\frac{2EK } {m} } (2)v=m2EK(2)
We put (2) in (1)
rpre=mpme(3)\frac{r_p}{r_e}=\sqrt{\frac{m_p}{m_e}} (3)rerp=memp(3)
where mp=1.67×10-27 kg, me=9.1×10-31 kg
Using (3) we got
rpre=42.8\frac{r_p} {r_e}=42.8rerp=42.8
Answer
42.8
