A point charge Q1=−2 μC is located at x=0, and a point charge Q2=+8 μC is placed at x=−0.5 m on the xaxis of a cartesian coordinate system.The goal of this problem is to determine the electric field, E⃗ (x)=E(x)xˆ, at various points along the xaxis
(a)What is E(x) (in N/C) for x=82.0 m ?
What is E(x) (in N/C) at x=0.17 m?
What is E(x) (in N/C) at x=34 m?
(b) At what point (apart from x=∞), is E(x)=0? Express your answer in meters.

The First is 7.901.
Just this in the moment. 
c) 46.244

b) 1283994.39504

and the 2) (B) is 0.5

SHOW YOUR WORK PLEASE. DO NOT JUST PUT THE ANSWER, BUT PUT THE WORK TO GET THE ANSWER. THANK YOU!

(a)What is E(x) (in N/C) for x=48.5 m ?
What is E(x) (in N/C) at x=0.1 m?
What is E(x) (in N/C) at x=96 m?
(b) At what point (apart from x=∞), is E(x)=0? Express your answer in meters.
