Question
What is the strength (magnitude) of the electric field due to the left hand object only at the location exactly halfway in between the two charged objects? what is the strength (magnitude) of the electric field due to the right hand object only at the location exactly halfway between the two charged objects? what is the strength of the net electric field due to the BOTH objects at the point halfway between the two charged objects? What would be the force on a proton placed at the point halfway between the objects?Explanation / Answer
let
q1 = +28 micro C
q2 = -28 micro C
d = 4.89 cm = 0.0489 m
a) at mid point,
|E1| = k*q1^2/d^2
= 9*10^9*(28*10^-6)^2/0.0489^2
= 2951 N/c
b) at point ,
|E2| = |E1|
= 2951 N/c
c) Enet = E1 + E2
= 2*2951
= 5902 N/c (towards -x axis)
d) Force on proton,
F = q*Enet
= 1.6*10^-19*5902
= 9.44*10^-16 N (towards -x axis)
