In order to calculate the electric field strength, we may use the formula:E = kQ/d²Where Q is the charge and d is the distance between the charge and the test charge. Substituting the values into the equation:E = (9 x 10⁹) (8.7 x 10⁻⁹) / (3.5²) E = 6.39 Newtons per coulombTherefore, the answer is 6.4 Newtons/coulomb
