Please help with part A and C

Four long, parallel conductors carry equal currents of I = 5.20 A. The figure below is an end view of the conductors. The current direction Is Into the page at points A and B and out of the page at C and D. C B (a) Calculate the magnitude of the magnetic field at point P, located at the center of the square of edge length { = 0.200 m. X Superposition allows us to calculate the field of each wire and then add them to find the total field. PT (b) Determine the direction of the magnetic field at point P, located at the center of the square of edge length { = 0.200 m. to the left to the right @ upward O downward into the page out of the page (c) What If? What would be the magnitude and direction of the Initial acceleration of an electron moving with velocity 3.53 x 10 m/s Into the page at point P? magnitude 6.2106 x m/s2 direction to the right Need Help
