Question

Problem 17.40 Two point charges are separated by 25.0 cm (see the figure(Figure 1) ). Assume that q1 = 6.20 nC and q2 = 15.0 nC .

Part A Find the magnitude of the net electric field these charges produce at point A. E = m N/C

Part B Find the direction of the net electric field these charges produce at point A. Find the direction of the net electric field these charges produce at point . The field is directed to the right. The field is directed to the left.

Part C Find the magnitude of the net electric field these charges produce at point B. E = m N/C

Part D Find the direction of the net electric field these charges produce at point B. Find the direction of the net electric field these charges produce at point . The field is directed to the right. The field is directed to the left.

Part E What would be the magnitude of the electric force this combination of charges would produce on a proton at A? F = m N

Part F What would be the direction of the electric force this combination of charges would produce on a proton at A? What would be the direction of the electric force this combination of charges would produce on a proton at ? The force would be directed to the right. The force would be directed to the left.

Answer 1

B) Direction of the net electric field at point A due to two point charges is towards right, which is towards q2. C) Magnitude of net electric field at B is 9x1Ơ x 10 x(15+620) 0.102 +0.352 Ener=-1440 x 10,n NC D) Direction of net electric field at B is towards right. E) Proton is situated at point A. The resultant force is due to both the charges. II91 1 -429 q-Charge of the proton et_ 9x109 x10-9x(15-620)×1.6×10-19 0.102 -0.15 Frt10.13x10 N
