When a test charge qo 2 nC is placed at the origin, it experiences a force of 8 x 10-4 N in the positive y direction (a) What is the electric field at the origin? N/Cj (b) What would be the force on a charge of -4 nC placed at the origin? Nj (c) If this force is due to a charge on the y axis at y-3 cm, what is that charge (magnitude and sign)? eBook
