Question 4: Sphere in Fields Phenomenon: A positively charged sphere with charge q-2.00 x 10-19 C and mass m- 3.25 x 10-27 kg is traveling in a straight line in the (-) direction. The sphere interacts with an external electric field EExt--,4001 블, and an external magnetic field BExt-1.7n Ext out of page The Big Question we are trying to answer is how fast is the sphere moving? We will answer in steps Ext (a) What is/are the relative magnitude(s) and direction(s) of the force(s) on the sphere that result in a constant velocity--vj? Tell me your answer by drawing a Force Diagram of the sphere on the graph paper (b) Off to the side of your force diagram, add the all the forces acting on the particle tip to tail. Should there be a net force, 2Fomsphere? Think about the motion of the sphere. (c) Use your force diagram to write an algebraic representation of 2Fon. sphere. [Hint: if your forces are only in one dimension, drop the vector hats and apply negatives for force(s) that point left and positives to force(s) that point right.] (d) Substitute the definitions of the forces you have in algebraic representations. [Hint: since you figured out the direction of your forces in the previous question, use magnitude definitions]. (e) Now, solve for the unknown to answer the Big Question of how fast is the sphere moving?
