Question

Shown above is a region with a magnetic field into the page, the trajectory of a number of particles and information about the particles. After analyzing this information answer the following questions.

Particle: Radius: Mass: Charge: Velocity

#1            infinite

#2             3r        m         q           3v

#3             r        2m         q      

#4                                    2q          v

#5            2r       10m                      2v

A) Which particles contain no electronic charge?

My answer: #1

B.) Which particles contain a positive charge? [Am absolutely lost on this one]

C.)Comparing particles #2 and #3, which has the greater speed?

D.) Comparing particles #2 and #4, which has the greater mass?

E.) Comparing particles #2 and #5 which ahst he greater electronic charge(we are comparing magnitude of charge).

Lifesaver rating to whoever helps.

Explanation / Answer

B) #2, #3, #4 C) mv = qBr, so (m2/m3)*(v2/v3) = (q2/q3)*(r2/r3) given m2/m3 = 1/2, q2/q3 = 1, r2/r3 = 3 so 1/2 *(v2/v3) = 3 v2/v3 = 6 answer: v2 has greater speed D) (m2/m4)*(v2/v4) = (q2/q4)*(r2/r4) from the graph, r2/r4 < 1 (m2/m4)*3 < (1/2)*1 m2/m4 < 1/6 answer: m4 has greater mass E) (m2/m5)*(v2/v5) = (q2/q5)*(r2/r5) (1/10)*(3/2) = (q2/q5)*(3/2) so q2/q5 = 1/10 answer: q5 has greater charge.
