One electron, which is initially at rest, was released in a uniform electric field. It accelerated horizontally to the right direction and travelled 250 cm after it was released for 5 us. Assuming that the effect of gravity is negligible, determine the electric field's magnitude and direction. a. 1.1 N/C (to the left) b. 1.1 N/C (to the right) c. 0.57 N/C (to the left) d. 0.57 N/C (to the right)
