A particle (mass 6.7×10-27 kg, charge 3.2×10-19C) moves along the positive x axis with a speed of 4.8x105m/s.
A particle (mass 6.7×10-27Â kg, charge 3.2×10-19C) moves along the positive x axis with a speed of 4.8x105m/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?
