A proton is placed in a 4:36 x 10 N/C electric feld. Calculate the magnitude of the intial electric force acting on the proton. You can find the charge of a proton on your Physics 30 data sheet. e a. 6.98 x 10 19 N b. 6.98 x 10-15 N O c. 2.71 x 10 12 N d. 1.40 x 10-14 N A 0.46 N force is exerted on a negatively charged particle by a 1.32 x 10* N/C [south] electric field. Determine the charge on the particle, and the direction of the acceleration of the particle. a. 3.48 x 10"- C, and the particle will accelerate south b. 3.48 x 10"1 C, and the particle will accelerate north c. 3.48 x 10 1 C, and the particle will accelerate north O d. 3.48 x 10"5 C, and the particle will accelerate north
