Question

1) Why is it safer to stay inside your car during a lightning storm?

a. A car is possibly the most dangerous places to be in a lightning storm.

b. Rubber tires make it nearly impossible for lightning to pass through the car into the ground.

c. Because electrons in the metal shield the electric field from the passengers inside the car.

d. Because a car body is smooth with relatively few points to attract lightning.

2) Say there's an electric field and corresponding equipotential lines. If a charge moves from Point A to Point B, what happens to its potential energy?

a. It rises if it is a negative charge, but lowers if it is a positive charge.

b. It lowers if it is a negative charge, but rises if it is a positive charge.

c. It stays the same.

d. It rises regardless of whether it is a positive or negative charge.

e. It drops regardless of whether it is a positive or negative charge.

Answer 1

1) In strong electric fields, rubber tires actually become more conductive than insulating.

So option B is correct.

2) In this case When a positive charge moves in the direction of the electric field the field does positive work on itand the potential energy decreases.

So option A is correct.

Hope this will help you. Please give a thumbs up. Thanks.
