SUMMARY
The electric field (E) at a charge can be calculated using the formula E = F/q, where F is the force experienced by the charge and q is the magnitude of the charge. In this case, a 4C charge experiences a force of 45i N, leading to an initial calculation of E = 45/4 = 11.25 N/C. However, the correct representation of the electric field should include the directional component, resulting in E = 11.25i N/C. The confusion arises from the interpretation of the force vector and its components.
