Exercise 1 Electric Fields In this exercise, you will use a digital multimeter to collect voltage data to graph electric fields.

Lyrx [107]

Answer:

The answers are in the explanation section below

Explanation:

1) The generalization that can be made from the exploration is that as we move away from the positive electrode, the potential energy gets lower. If we move away from the negative electrode, then the potential energy becomes higher.

2) The positive test charge will have the least potential energy when it gets to the negative electrode point.

3) To move one electron 1m in a direction along one of the equal potential lines, there is no energy needed. Zero work will be required for a charge to move on the equipotential line.

4) If lightning strikes a tree 20m away, it would be better to face the tree or have our back facing the tree. This is because the equipotential line will be present at the point where our body stands, this will protect from electric shock.

The pattern to be sketched is attached.

The crew of a cargo plane wishes to drop a crate of supplies on a target below. To hit the target, when should the crew drop the

lara [203]

To hit the target the crew drop the crate before the plane is directly over the target. It is because because the cargo has forward velocity and therefore before it reaches the ground it travels some distance. The answer is A. Hope it helps.
