Tip 1:

Observe the figure:

The 2 suggest charges are positive, therefore

*

*

The angle of the area at the dot from the optimal charge is

*
.

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

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

*
.

Electric area as a result of charged particle is

*
, where

*
is the permittivity of totally free room
*
.

*
is the charge of the electron.

*
is the distance between the two suggest charges.

Tip 2:

The distance between the peak charge and also the dot is

*
.

For the charged particle along top surconfront is

*
.

*

*

*

The distance in between the bottom charge and the dot is

*
.

For the charged pshort article alengthy optimal surchallenge is

*
.

*

*

*

Step 3:

Find the net electrical area.

*
is amount of horizontal and vertical components.

Find the amount of horizontal components.

*

Find the amount of vertical components.

*

Because of this

*
.

Find the magnitude of electrical field stamina.

*

Strength of the electric field is

*

Find the direction of electrical area.

*

*

Direction of electric area is

*
above the
*
-axis.
