A charge of 50-μC is placed on the y axis at y = 3.0 cm and a 77-μC charge is placed on the x axis at x = 4.0 cm. If both charges are held fixed, what is the magnitude of the initial acceleration of an electron (me = 9.1 x 10-31 kg) released from rest at the origin?

Explanation:

Given that,

First charge, . It is placed at y = 3 cm

Second charge, . It is placed at x = 4 cm.

Force on electron due to q₁.

Force on electron due to q₂.

The net force on the electron is given by :

Let a is the acceleration of the electron. Net force is given by :

F = ma

So, the acceleration of the electron is .

as we know our atmosphere or air have different levels. every level has other gasses, and every gas has another permeability. when the light comes from lower permeability to higher permeability, it changes its direction. so that means that when the light comes from the moon to the earth, it changes it's direction many more times. it basically means that the shape of the light part of the moon is changed on the earth.
