Step 1:

Observe the figure:

The two allude charges space positive, therefore

*

*

The edge of the ar at the dot from the top charge is

*
.

You are watching: What is the strength of the electric field at the position

The angle of the field at the dot from the botton charge is

*
.

Electric field because of charged bit is

*
, where

*
is the permittivity of free space
*
.

*
is the charge of the electron.

*
is the distance in between the two suggest charges.

Step 2:

The distance in between the optimal charge and the dot is

*
.

For the charged bit along peak surface is

*
.

*

*

*

The distance between the bottom charge and the period is

*
.

For the charged fragment along top surface is

*
.

*

*

*

Step 3:

Find the net electric field.

*
is sum of horizontal and vertical components.

Find the sum of horizontal components.

*

Find the sum of upright components.

*

Therefore

*
.

Find the size of electric field strength.

*

Strength the the electric field is

*

Find the direction of electrical field.

*

*

Direction of electrical field is

*
over the
*
-axis.
