A small charged particle (mass = 240 µkg ; charge = + 480 µcoul) travels through a region of space where the gravitational field is negligible ; however, there are both electric and magnetic fields. At a certain point where the magnetic field is 3î + 2j+ 2k (T), the particle has a ve- locity of 1440î + 960ĵ (m/sec) ; if at this point the particle's acceleration is zero then what is the electric field? (in N/coul) a. Ē = 1920î + 2880j b. Ē = - 1920î + 2880j с. Ё 3D0 d. Ē = - 1920î - 2880j e. Ē = 1920î - 2880ĵ
