Question

A solid gold sphere is placed in an external electric field. Which of the following statements is true? The electrons move to the left, thereby leaving a positive charge on the right The electrons move to the right, thereby leaving a positive charge on the left The electrons move such that the total electric field inside is zero None of the above A positively charged rod is brought near the top knob of a gold-leaf electroscope. They are not in contact with each other. Still, the leaves of the electroscope repel each other. What charge is on the leaves? Positive Negative Could be either Not enough information is given to answer this question Which of the following objects is positively charged: An electron A hard plastic rod rubbed with fur A Ziploc bag rubbed with glass rod None of the above Which of the following charge configurations will NOT result in a zero electric field at the center (the shapes are: Equilateral triangle, squares and circle): A small metal-coated sphere is attracted to a negatively charged rod. What can you conclude about the sign of the charge on the sphere? The sphere is positive or neutral The sphere is positive or negative The sphere is negative or neutral Nothing can be concluded Drawings 1 and 2 show two examples of electric field lines. Which of the following statements is true?

Explanation / Answer

7) this is a triky question 'cause statements a) and b) are true! but in order to confirn this we need the electric field direction, in this case there is not provide so, we can't say if this statement are realy true. The statement c) is true in any case that involve conductors, because in conductors the electric field inside is zero ever, as consecuence the charge is uniformly distibuted on their surface, Therefore the correct answer is:

c) is the unique true statement.

I can help you with the other questions, but you need post again as a new question
