- 3An alien from a planet in the galaxy M31 (Andromeda) has a ray gun that shoots protons at a speed of 2.0 × 10^5 m/s. Design a magnetic shield that will deflect the protons away from your body. A) Suppose that the magnetic field has horizontal direction and you want to deflect the beam through a path with radius R = 2.0 m as shown in (Figure 1). Find the field strength needed to achieve the desired deflection. The mass of a proton is 1.67× 10^−27 kg and its charge is 1.6× 10^−19 C. B) What is the direction of the magnetic field in the region defined in (Figure 1), that would cause the deflection shown for the proton beam? along the path of the proton beam into the page toward the center of the curved path out of the page C)What is the direction of the magnetic force in the region defined in (Figure 1), that would cause the deflection shown for the proton beam? along the path of the proton beam into the page toward the center of the curved path out of the pageAn electron is moving to the right when suddenly a magnetic field is switched on that points out of the page.
