Step 1:

Observe the figure:

The two allude charges space positive, therefore

*

*

The angle of the field at the period from the peak charge is

*
.

You are watching: What is the strength of the electric field at the position indicated by the dot in (figure 1)?

The angle of the ar at the period from the botton charge is

*
.

Electric field due to charged bit is

*
, where

*
is the permittivity of free space
*
.

*
is the charge of the electron.

*
is the distance in between the two point charges.

Step 2:

The distance between the top charge and the period is

*
.

For the charged fragment along peak surface is

*
.

*

*

*

The distance in between the bottom charge and also the period is

*
.

For the charged fragment along peak surface is

*
.

*

*

*

Step 3:

Find the net electric field.

*
is amount of horizontal and vertical components.

Find the sum of horizontal components.

*

Find the amount of upright components.

*

Therefore

*
.

Find the size of electric field strength.

*

Strength the the electrical field is

*

Find the direction of electric field.

*

*

Direction of electrical field is

*
above the
*
-axis.
