v=2.2E5 m/s

l=0.16 m

I=5.3 A

N=820

mp=1.67E-27 kg

B=3.4E-2 T

Looking for radius of curvature in the solenoid with the above variables.

## Homework Equations

BIl=F

## The Attempt at a Solution

BIl=mv^2/r

3.4E-2*5.3*0.16=1.67E-27*(2.2E5)^2/r

r=2.8E-15 m

The correct answer however, is 6.8E-2 m, so what did I do wrong?
