Skip the next Go to No next a few circular-flow demonstrations, etc. No. 11 on that page: -A source and a constant ow by unknown charges, what can we conclude? in the observing window, there isare the observing area, they might be the observing area, they might be this vector field looks like the created by field Within the observing Above the observin Below the ob (how many point charge(s). _(positive or negative) charges. _(positive or negative) charges. The charges above (a few point charges harges above or below the observing areas seem to be w point charges or continuous and uniformly distributed charges) here. Answer the following two questions and then Go to Part 2 So two vectors are perpendicular to each other, their dot product is zero or peaches maximum) two vectors are parallel to each other, their cross product (is zero or reaches maximum) If there is time left at the end, come back to the page of Vector Field and play with the remains demonstrations. Electrostatics The field of a positive point charge. Observe E field strength, which is represented by the length of the red arrow. When the observer is moved further away or closer to the charge, the observed E field strength will (increase or decrease). Explain why: Notice the direction and size of the Efield observed at different location. Draw arrows of correct relative length along the correct directions to show the field observed at the following 4 locations marked as small dots. (The large circle represent the positive charge.)
