5. A particle (mass = 6.70 x 10-27 kg, charge = +1.60 x 10-19 C) moves along the positive-x axis with a velocity of 4.80 x 104(1) m/s. It enters a region of uniform electric field; the uniform field is in the negative-x direction: E = E(-1). The particle comes to rest after moving 2.00 m into the field. What is the magnitude of the electric field, E? a. 1.22 N/C b. 6.04 N/C c. 13.5 N/C d. 19.0 N/C e. 24.1 N/C
