1. An electric force with a magnitude of 2.5 N, directed to the left, acts on a negative charge of 5.0 C. (a) Determine the electric field in which the charge is located. [ans: 0.50 MIC [toward the right]] 0)) Calculate the electric field when the force is the same but the charge is 0.75 C. [ansz 3.3 NIC [toward the right]: 2. Calculate the magnitude and direction of the electric field at a point 2.50 m to the right of a positive point charge q = 6.25 x 10'6 C. [ans: 3.99 x to3 we [toward the right]]
