A positive charge q is fixed at point (3, 4) and a negative charge -q is fixed at point (3, 0). 4- 0 9 Determine the net electric force Fnet acting on a positive test charge +Q at the origin (0, 0) in terms of the given quantities 3- and physical constants, including the permittivity of free 2- space co. Express the force using ij unit vector notation. Enter precise fractions rather than entering their approximate 1- numerical values. r - q -4 -3 -2 -1 2 4 -1- 90 98 Fnet = 4 -2- 4 TLE 1125 125 -3- 4
