Determine the magnitude and direction of the electric field at a point midway between a –8.0 µC and a +5.8 µC charge 6.0 cm apart. Assume no other charges are nearby.

Respuesta :

The magnitude and direction of the electric field is equal to 3.45 x10^13 N/m and the direction in towards the negative charge.

Electric field

To calculate the electric field of a point it is necessary to use the following expression:

                                             [tex]E = k\frac{Q}{d^{2}}[/tex]

Thus, calculating the field formed by each charge we have:

  •  –8.0 µC

   

                                    [tex]E = 9 \times 10^{9} \times \frac{8}{36\times 0.0001}[/tex]

                                      [tex]E = 2\times 10^{13} V/m[/tex]

  • +5.8 µC

                                   [tex]E = 9 \times 10^{9} \times \frac{5.8}{36\times 0.0001}[/tex]

                                    [tex]E = 1.45 \times 10^{13} N/m[/tex]

The direction of the electric field of the negative charge is towards the charge (attracted) and of the positive charge is repelled.

So, we can add the two values ​​of field found, since the two are directed towards the negative charge, so that :

                                       [tex]E = 2 \times 10^{13} + 1.45 \times 10^{13}[/tex]

                                       [tex]E = 3.45 \times 10^{13} N/m[/tex]

So, the magnitude of eletric field is equal to 3.45 x10^13 N/m and the direction in towards the negative charge.
