1a. A positive particle of charge 5 C sits stationary [locked tothe ground] 3.5 meters from a negatively charged particle, withcharge 2 C. How strong is the force the negative particleexperiences? How does that compare if the negative particle is 7meters away? Both charges have mass of 5 grams; how fast does thenegatively charged particle accelerate in both cases?
b. What force does a particle with a charge of +5 C, moving at10 m/s feel when moving *perpendicular* to a 3 Tesla magneticfield? What about if it moves parallel to the field?
c.Which process will produce a higher energy form of light? Afree electron being captured at the n = 2 energy level, or n =1?
