nt PRINTER VERSION BACK NEXT Chapter 21, Problem 07 A magnetic field has a magnitude of 0.0011 T, and an electric field has a magnitude of 5.0 x 103 N/C. Both fields point in the same direction. A positive 2.6-pC charge moves at a speed of 3.3 × 106 m/s in a direction that is perpendicular to both fields. Determine the magnitude of the net force that acts on the charge.

Explanation / Answer

Fb = q (v x B) = (2.6 x 10^-6)(3.3 x 10^6 0.0011)

Fb = 9.438 x 10^-3 N out of page

Fe = q E = (2.6 x 10^-6) (5 x 10^3)

Fe= 0.013 N up the page

F = sqrt(Fe^2 + Fb^2) = 0.016 N ....Ans
