Question

please, explain how you get to the answer by showing how the formulas are used.

I have a charge 2m from a point P.  The electric field it produces at P is 400N/C and points directly toward the charge.  What is the charge?

Two charges a distance r apart attract each other with a force of 5N.  What will be the force if I triple the distance between them?

Explanation / Answer

since the direction of electric field is toward the charge

the charge is negetive

F=5N;

F=K*q1*q2/r^2

if r=3r

F1=K*q1*q2/(9*r^2)

F1=F/9=5/9N

F1=0.5556N
