(A) what explanation is used today to explain how electrical forces are able to act upon objects at a distance?


(B) newtons theory explained electrical attraction at a distance. what kind of electrical phenomena at a distance did it fail to explain? How does the modern explanation you stated in part (A) account for this second kind of action at a distance

Explanation / Answer
