Question
Exercise 21.40 A-4.00 nC point charge is at the origin, and a second -5.00 nC point charge is on the z-axis at 0.800 m. Part A Find the electric field (magnitude and direction) at point on the z-axis at 0.200 m. Express your answer with the appropriate units. Enter positive value if the field is in the positive z-direction and negative value if the field is in the negative r-direction. 774, Submit My Answers Give Up Correct Part B Find the electric field (magnitude and direction) at point on the z-axis at ar 1.20 m Express your answer with the appropriate units. Enter positive value if the field is in the positive z direction and negative value if the field is in the negative z-direction. E -306 N.

Enter positive value if the field is in the positive z-direction and negative value if the field is in the negative z-direction. 944, N My Answers Give Up Submit CorrectExplanation / Answer
d)
Net electric force at x=0.2 m
F=(-1.602*10-19)*(-774)=1.24*10-16 N
e)
at x=1.2 m
F=(-1.602*10-19)*(-306)=4.9*10-17N
f)
at x=-0.2 m
F=(-1.602*10-19)*(-944)=-1.51*10-16 N
