Suppose a negative point charge is placed at x = 0 and an electron is placed at some point P on the positive x-axis. What is the direction of the electric field at point P due to the point charge, and what is the direction of the force experienced by the electron due to that field?

O E along -X; F along –X
O E along +x; F along +x
O E along –x; F along +x
O E along +x; F along - x

Respuesta :

Answer:

E along –x; F along +x

Explanation:

  • When a negative point charge is placed at x=0 and an electron is place at any point P on the positive x-axis the as we know that the like charges repel each other, but there will be no change in the natural tendency of the individual electric field lines.
  • So the direction of the electric field lines at point P due to the point charge will be towards the negative x-axis.
  • The direction of force on the electron due to the electric field of point charge at x=0 will be towards positive x-axis in accordance of the repulsion effect.
