Question
The diagram below shows a dipole centered at the origin and along the x-axis. Determine an expression for the total electric field at a point A (r0 = 3.8L,0) in terms of q and L. Calculate the magnitude of the total electric field at A, when q = 2.35 x 10-07 C and L = 24.2 cm.
Correct, computer gets: 3.04E+03 N/C

Consider the situation as described in the diagram (in the previous problem), and the following statements. If the statement is true, answer `T', if it is false, answer `F', and if the answer cannot be determined from the information provided, answer `C'. For example if `A' and `E' are true and there is not enough information to answer `C' and the rest are false, then answer `TFCFTF'.
A) The direction of the net electric field at A is E
B) The direction of the net electric field at the origin is E
C) The magnitude of the net electric field at point A is greater than the magnitude of the net electric field at the origin.
D) The direction of the net electric field at a point on the negative y-axis is S
E) The direction of the net electric field at the point (-r0,0) is E
F) The direction of the net electric field at a point on the positive y-axis is NW
PLEASE JUST ANWSER NUMBER 2,THANKS
Explanation / Answer
A)the direction of electric field at A is towards East is TRUE
B)the directionn of electric field at origin is towards East is FALSE. It is towards west.
C)the net electirc field at A is less than the net electric field at origin. So the statement is FALSE
D)The net electric filed on negatve y-axis is towards west. So statement is FALSE.
E)The net electirc field on negative x-axis towards East. So statement is TRUE.
F)The net electric filed on positive y-axis is towards west. So statement is FALSE
