Answer with Explanation:
We are given that


a.x=-0.2 m

Where 
Net electric field=E+E'=4500+1237.5=5737.5 N/C
b.x=0.20 m
Net electric field=E-E'=4500-1237.5=3262.5 N/C
c.y=0.20 m
E=1237.5 N/C
Net electric field=
Answer:
true
Explanation:
Newton is the measure of the force with turns to be gravity multiplying the mass. Thus, the forces acts on the particles in the direction of the movement of the particles
