Question



PROBLEM 2 - A particle of charge +12 HC and mass 3.8 x 10 kg is released from rest in a region where there is a constant electric field of +480 N/C. What is the displacement of the particle after a time of 1.6 × 10 s? Let the electric force be the only force acting on the particle. Hint: Is the acceleration constant? Recall the equations of motion for constant acceleration: 2
