brought near a larger positively Charged object how are 1. When a neutral object the negative charges organized? 2.How are neutral objects positively charged by conduction? Provide evidence to support your answer ?

TRUE OR FALSE ANSWER 10 AND 12 10.The chain seen dangling from the rear of a gasoline truck is to let excess charges on the truck to be grounded. 12.It is important to avoid sharp edges or points on conductors used in high-voltage equipment because a sharp point on a charged conductor would produce a large electric field in the region near the point and an electric discharge could most easily take place at the point.

2. DETAILS KATZPSEF1 23.P.023. MY NOTES ASK YOUR TEACHER Two coins are placed on a horizontal insulating surface a distance of 2.4 m apart and given equal charges. They experience a repulsive force of 4.4 N. Calculate the magnitude of the charge on each coin. Submit Answer

Is the electroscope below able to detect the charge sign introduced to its leaves? Explain your answer. Hint: The leaves repel each other when they are charged in such a way that the rods attached to the leaves make an angle of ? relative to each other.

Diagram of the problem, necessary formulas, clearance and numerical solution. Two small spheres have a center-to-center separation of 1.5 m. They carry identical charges. Approximately how large is the charge on each if each sphere experiences a force of 2 N?.

1. Electrostatic charge build-up in clouds - When a neutral (uncharged) cloud swirls and rises rapidly, there is a lot of friction between water molecules and air. If the base of the cloud becomes negatively charged, why does this mean that the top of the cloud becomes positively charged? Explain. 2. Look at the picture below and explain why the earth gets positively charged when a cloud (whose base is negatively charged) hovers over it? What type of charging process occurs? ایمنی سیصد étrie منافقين
