3. In the figure below the electric field has a magnitude of 2.50kV/m and the magnetic field in all regions has a magnitude 0.3507. The region on the left with both electric and magnetic fields is the velocity selector, the region on the right has no electric field and is called the deflection chamber. A proton travels in a straight line through the velocity selector and enters the deflection chamber. Figure 2: Velocity Selector (a) What is the kinetic energy of the proton? (b) What is the radius of curvature of the proton's path in the deflection chamber?
