I need help with parts A&B please

Extracted text: Part A Charges -q and +2q in (Figure 1) are located at x = £a. Determine the electric field at point 1. Write the field in component form. Express your answer in terms of the variables q, a, unit vectors i, j, and electrostatic constant K. Use the 'unit vector' button to denote unit vectors in your answer. Figure 1 of 1 y 2a 1 a- Part B 3 - 2a +29 2a Determine the electric field at point 2. Write the field in component form. -a- Express your answer in terms of the variables q, a, unit vectors i, j, and electrostatic constant K. Use the 'unit vector' button to denote unit vectors in your answer. -2a +4
