Question

Two point charges are placed on the x axis as shown in (Figure 1). The first charge, q1q1q_1 = 8.00 nCnC , is placed a distance 16.0 mm from the origin along the positive x axis; the second charge, q2q2q_2 = 6.00 nCnC , is placed a distance 9.00 mm from the origin along the negative x axis.

 

A. Find the x-component of the electric field at the origin, point O.

Express your answer in newtons per coulomb to three significant figures, keeping in mind that an x component that points to the right is positive.
 

B. Now, assume that charge q2q2 is negative; q2=−6nCq2=−6nC, as shown in (Figure 2). What is the x-component of the net electric field at the origin, point O?

Express your answer in newtons per coulomb to three significant figures, keeping in mind that an x component that points to the right is positive.
