Review for 2326 exam References Mailings Review ViewTell meat -y.A- 2 .2.-. 11Nerm aNo Spac -Heading 1 Heading 2 Title Subtitle-5 Paragraph Styles 8. Calculate the time constant of the circuit. What will be the current in R1 at time-? R2 C2 Chapter 29 9. A 1.50-C charge moves with a velocity of (3.0i-2.0j + 6.0k) m/s and experiences a magnetic force of (4.0i - 10j+ 12k) N. The x component of the magnetic field is equal to zero. Determine the y component of the magnetic field 10. A charged particle (mass 4.0, charge-12.0K) moves in a region where the only force on it is magnetic. What is the magnitude of the acceleration of the particle at a point where the speed of the particle is 20,000 m/s, the magnitude of the magnetic field is 1.20 T. The particle is moving perpendicular to the magnetic field. 11. For the particle in the previous problem, what should be the electric field that would give the same force as the magnetic field in the previous problem.

Explanation / Answer

8]time constant = RC = [20*10/(20+10)]*[30e-6+60e-6] = 0.0006 s answer

current in R1, i = E/R1* e^-0.5

= E/20* e^-0.5 = 0.0303 E where E is emf ANSWER
