A particle (mass = 6.7 10-27 kg, charge = 3.2 10-19 C) moves along the positive x axis with a speed of 4.8 105 m/s. It enters a region of uniform electric field parallel to its motion and comes to rest after moving 2.0 m into the field. What is the magnitude of the electric field?
a. 2.0 kN/C
b. 1.5 kN/C
c. 1.2 kN/C
d. 3.5 kN/C
e. 2.4 kN/C
Question 2
A particle (charge = +2.0 mC) moving in a region where only electric forces act on it has a kinetic energy of 5.0 J at point A. The particle subsequently passes through point B which has an electric potential of +1.5 kV relative to point A. Determine the kinetic energy of the particle as it moves through point B.
a. 3.0 J
b. 2.0 J
c. 5.0 J
d. 8.0 J
e. 10.0 J
