Two charges q1 = +4 nc (positive) and q2 = -2 nc (negative) are arranged in a line. q1 is at the origin (x-0) and q2 is at x=4 m. what is the electric field at the point x 1 m on the same line? let sign of the electric field indicate the direction; positive is towards larger x and negative is towards smaller x. 38 n/c 13.5 n/c 4.5 n/c 34 n/c
