Answer 1

a)The electric field in the plane that bisects the charged rod is, The electric field at a point p, (0.01 m )due to left side rod is, 10x10-9 E - (9x109 20.11 0.01,0.01 1.61x10 N/C The electric field at a point p, (0.03 m) due to right side rod is, 10x10-9 (9x 109 ight 0.08 (00301 0.03,00.03)+ 2 -0.47x105 N/C The net electric field at point p, is, (1.61x10)-(0.47x10) 1.14x10 N/C 1.1x10 N/C (two significant figure) b) The electric field at a point P, (0.02 m) due to left side rod is, 10x10 E (9x10) 2 ,(0.11 0.02,/(0.02)+- -7.68x104 N/C The electric field at a point p' (0.02 m) due to right side rod is. 10x10-9 Ern" (9x10%) 0.02,(0.02)1 2 0.11 2 -7.68x104 N/C

The net electric field at point p, is, EErigit (7) 7.68 x104)-7.68 x10 0 c) The electric field at a point p, (0.03 m) due to left side rod is, -9 10x10 0.03.(0.03 2, (0.11 2 0.47x10 N/C The electric field at a point p, (0.02 m)due to right side rod is, 10x10-9 2 0.11 0.01,1(0.01) 1.61x105 N/C The net electric field at point p is E,-Elet-Eight (0) --1.14x10 N/C -1.1x10 N/C(Two significant figure) 0.47 x105)-(1.61x10 Negative sign indicates the direction of the electric field towards right side
