Answer:
The ball will be attracted to the negatively charged plate. It'll touch and pick up some electrons from the plate so that the ball becomes negatively charged. Immediately the ball is repelled by the negative plate and is attracted to the positive plate. The ball gives up electrons to the positive plate so that it is positively charged and suddenly attracts to the negative plate again, flies over to it and picks up enough electrons to be repulsed by negative plate and again to the positive plate and that continues.
Answer: 2.74
Explanation:
We can solve this problem using the stopping distance formula:
Where:
is the distance traveled by the car before it stops
is the car's initial velocity
is the coefficient of friction between the road and the tires
is the acceleration due gravity
Isolating :
Solving:
This is the coefficient of friction
