Question

a point charge of -4.00nc is the origin, and a second point charge of +6.00nc is on the x axis at x=0.800m. Find the magnitude and directin of the electric field at each of the following points on the x asix : a) x =20.0 cm b) x=1.20 m c) x = -20.0 cm

Answer 1

sketch the diagram. Notice the E field points toward the negative charge due to the negative charge, and away from the + charge due to it. In between x=0 and x=.8, they both point toward the negative charge.

Answer 2

E= 131 N/C

Answer 3

E= 131 N/C
θ = 12.6 ∘ up from the negative x axis

Answer 4

None
