-This question has two parts

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 = 3.6L,0) in terms of q and L.  Calculate the magnitude of the total electric field at A, when q = 7.60 x 10-07 C and L = 50.0 cm.

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 = 3.6L,0) in terms of q and L. Calculate the magnitude of the total electric field at A, when q = 7.60 x 10-07 C and L = 50.0 cm. 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'. The direction of the net electric field at the origin is W The direction of the net electric field at a point on the negative y-axis is SE The magnitude of the net electric field at point A is greater than the magnitude of the net electric field at the origin. The direction of the net electric field at the point (-r0,0) is W The direction of the net electric field at a point on the positive y-axis is W The direction of the net electric field at A is W

Explanation / Answer

electric field at x units on central axis due to dipole is EF = 2P/4 pi eo r^3

where P = 2a q here P= 2* 0.5 * 7.6uC = 7.6 u N/C

thus EF = 2* 7.6*10^-6/ (4*3.14*8.85*10^-12 * ( 3.6*0.5)^3

Ef =1.40*10^5 N/C

A) The direction of the net electric field at the origin is W---------------true

B) The direction of the net electric field at a point on the negative y-axis is SE-------false

C) The magnitude of the net electric field at point A is greater than the magnitude

of the net electric field at the origin.--- false

D) The direction of the net electric field at the point (-r0,0) is W-------------true

E) The direction of the net electric field at a point on the positive y-axis is W----flase

F) The direction of the net electric field at A is W----------true
