Question: A positive charge q = 3.20 x 10-19 C moves with a velocity v = (2i + 3j - k) m/s through a region where

A positive charge q = 3.20 x 10-19 C moves with a velocity v = (2i + 3j - k) m/s through a region where both a uniform magnetic field and a uniform electric field exist.
(a) Calculate the total force on the moving charge (in unit-vector notation), taking B = (2i + 4j + k) T and E = (4i - j - 2k) V/m.
(b) What angle does the force vector make with the positive x axis?
