2. An object with charge of -54.0 nC is placed 11.2 cm above the origin on the +y-axis. A second object with charge of +42.0 nC is placed on the +x-axis 6.60 cm to the right of the origin.

a. Find the magnitude and direction of the electric field at the origin.

Q1 = -54.0 nC 11.2 cm

Q2 = +42.0 nC 6.60 cm

     

b. Where would you place a -12.0 nC charged object to make the electric field at the origin equal to zero. (You can put your answer in (x,y) coordinates or direction and distance from the origin.)
