A. Determine the electric field strength at a point 1.00 cm to the left of the middle charge shown in the figure below. (Enter the magnitude of the electric field only.)

B.If a charge of −7.81 µC is placed at this point, what are the magnitude and direction of the force on it? help_outlineImage Transcriptionclose(a Determine the electric field strength at a point 1.00 cm to the left of the middle Charge sh in the gure below.

Step 1

(a) Electric field due to charge q1 = 6.00μC is towards right. Electric field due to charge q2 = 1.50μC is towards left. Electric field due to charge q3 = -2.00μC is towards right.The net electric field at the point 1.00 cm to the left of middle charge is,

Step 2

(b) Force F on the charge q = -...
