Procedure Part $1$: Finding the Field Strength around a single charged particle.

Click on the $+1nC$ charge $()$ and drag it out and place it so that the center of the cross is lined up with the intersection of two darker lines. Make a quick sketch of the electric field generated by a $+1nC$ charge in the "Step $1"$ portion of the data section. Complete the questions for Step $1$ in the analysis section. Replace the $+1nC$ charge with a $-1nC$ charge $()$

Click on the Electric Field box to turn off the arrows. Drag the yellow sensor and place it on the next intersection $(0\mathrm{.}50m)$ to the right of the positive charge. The sensor measures the strength of the filed in Volts per meter or V$/$m$.$ Make sure the angle of the sensor reads $0\mathrm{.}0$ degrees as in the first diagram below. Record the electric field strength at this position. Move the sensor to the intersection $0\mathrm{.}50m$ above the $+1nC$ charge. Make sure the angle reads $90\mathrm{.}0$deg. Record the field strength in the data chart. Record the direction with an arrow. Repeat this using an angle of $180\mathrm{.}0$ deg and an angle of $270$ deg $($which will appear on screen as $-90\mathrm{.}0$deg $).$ Record the field strength at each position. Try to center the sensor where the two lines cross.

Repeat step $2$ using an angle of $0$ degrees but moving the sensor from $0\mathrm{.}50m$ to $2\mathrm{.}0m$ in $0\mathrm{.}50m$ increments. Record the force vector arrow with both magnitude $($length of the arrow$)$ and direction.

Repeat step $2$ and $3$ by using a $+2nC$ charge. Drag a second $+1nC$ charge and place it on top of the first charge.

Remove both of the $+1nC$ charges by dragging them into the box at the bottom of the screen and replace them with a single $-1nC$ charge. Repeat steps $2$ and $3.$

Click on the "Electric Field" box to turn the arrows on$.$ Place $a+1nC$ charge on top of the $-1nC$ charge and describe what happens to the field. Record your observations.
