Electric fields point outwards from a positive charge and towards a negative charge.
1. Which of the following describes the electric field produced by the positive charge?
a. The electric field is directed radially toward the charge at all locations near the charge.
b. The electric field is directed radially away from the charge at all locations near the charge.
c. The electric field wraps circularly around the positive charge.
2. Now, let's look at how the distance from the charge affects the magnitude of the electric field. Select Values on the menu, and then click and drag one of the yellow E-Field Sensors. You will see the magnitude of the electric field given in units of V/m (volts per meter, which is the same as newtons per coulomb). Place the E-Field Sensor 1 m away from the positive charge (1 m is two bold grid lines away if going in a horizontal or vertical direction), and look at the resulting field strength.
Consider the locations to the right, left, above, and below the positive charge, all 1 m away. For these four locations, the magnitude of the electric field is_____
a. greatest above the charge.
b. greatest below the charge
c. greatest to the right of the charge.
d. the same
e. greatest to the left of the charge.
