A uniform magnetic field B⃗ , with magnitude 1.2 mT, is directed vertically upward throughout the volume of a laboratory chamber. A proton with kinetic energy 5.3 x 10-13 J enters the chamber, moving horizontally from south to north. The proton mass is 1.67 x 10-27 kg. (Neglect Earth’s magnetic field.) A series of statements are listed below. Identify the true statements. 1. The proton is deflected toward the east by the magnetic force, but its kinetic energy does not change. 2. During the deflection, the angle between the force vector and the velocity vector decreases from the initial 90o. 3. If the speed of the proton was increased before it enters the field, it would experience a greater force when it enters the magnetic field. 4. If a positively charged particle, with more mass than the proton but with the same speed enters this field, it would experience a smaller force when it enters this field. 5. The proton is deflected towards the east by the magnetic force, and the speed increases.
