Activ Physics: 11.4 Electric Field Point Charge (answers)

Electric field hockey simulation:

Level 1: Have the black puck as positive, set one red puck next to the black puck at the upper left corner of it and set another red puck down. Run simulation. It should repel the black pucks into the goal.

Level 2: Same setup from level 1 in order to go around the walls blocking. Place the red puck at the bottom of the field slightly more to the right.

Level 3: Have the black puck set to positive. Place a red puck down the initial position of the black puck. Have a blue puck place at top of the field next to the second wall. Have a 2nd blue puck at the other side of the  second wall parallel to the 1st blue puck. The black puck should be repelled by the red and attract by the two blue puck and into the goal.
