Hi Tutor, can you please help me with questions #8-14? Thank you very much.

A negatively charged particle, having a mass m = 5.89.]:1023 grams and a charge q = 1.603510"19 C, is released from rest in a uniform electric eld of magnitude 4000 NIC; the uniform electric eld points in the negative x direction, as shown in the figure. Assume that the force of gravity is negligible compared to the electric force acting on the charged particle. In the following. consider the period of time which starts at the instant when the particle is released [from rest) and ends at the instant when the particle has traveled a distance of 20.0 cm (along a straight line) in the uniform electric field.

C. the positive x direction. D. the negative x direction. 9. The magnitude of the electric force which the field exerts on the particle is equal to A. 6.40x1o-16 N. 13.4.00x103 N. c. 6.4ox103 N. n. 6.40x10-'9 N. E. 4000 N. 10. The work done on the particle by the electric force during the time it takes the particle to travel 20.0 cm in the electric field is A. 128 >
