8. A proton (q = 1.6×10-19 C and m = 1.67×10-27 kg) initially moves left to right along the x-axis at a speed of 2000 m/s. It moves into an E-?eld that points in the -x direction. The proton travels a distance of 0.200 m before coming to rest. Determine the acceleration (in m/s2) of the proton in the E-?eld.a. 4x107b. 3x107c. 2x107d. 1×1079. Determine the E-?eld magnitude that produces the acceleration in question 8.a. 0.3 N/Cb. 0.1 N/Cc. 0.7 N/Cd. 0.5 N/C
