Question

2. (1 point) Two metal spheres with different radii are each hanging from insulating nylon threads. One of the spheres has a net negative charge, while the other has no net charge. If the spheres are close together but do not touch, they will: A. attract each other B. repel each other C. repel if the sphere with the larger radius is the one that is negatively charged D. repel if the sphere with the smaller radius is the one that is negatively charged E. exert no force on each other

Answer 1

A. attract each other

Step-by-step explanation:

When the neutral sphere is brought close to the negatively charged, as charges can move freely in a conductor, some electrons will be repelled, leaving a net positive charge (equal in magnitude ot the charge in the other sphere) on the surface of the neutral sphere, which will cause that both spheres attract each other.
