Question
1. Two neural metal blocks are in physical contact side by side. Block A is on the left, and Block B is on the right. A negatively charged rod is brought near the left side of Block A. With the negative rod still present, the blocks separate. As a result, Block B will have a net charge that is? 8 A. Negative B. Positive C. Neutral but polarized D. Neutral and not polarized 2. A proton and an electron are near each other, and the static electric force is F. If the distance between the particles is halved then the new force of attraction is A. 4 F C. 2F D. 4F 3. Which of the following best describes insulators. A. Insulators are metals and do not allow charge to move easily through them B. Insulators are metals and allow charge to move easily through them C. Insulators are nonmetals and do not allow charge to move easily through them D. Insulators are nonmetals and allow charge to move easily through themExplanation / Answer
1) B) positive
2) D) 4*F
because, Force inversly proortional to square of the distance between the two charges.
3) C)
