WebbA) Paper is naturally a positive material. B) Paper is naturally a negative material. C) The paper becomes electrically polarized by induction. D) Rubber and paper always attract each other. E) The paper acquires a net positive charge by induction. C. Five styrofoam balls are suspended from insulating threads. WebbBecause the membrane is held together by the attraction of opposite charges, it is possible to overcome this attraction by applying a large electric potential across the membrane. In some cells, applied electric potentials are used to open and close the cell membrane in order to allow nutrients and waste to enter and exit the cell.

WebbAlright. The first step will be determining the directions of the forces generated on q3 due to q1 and q2 by considering the sign of the pair of these charges. Well, q1 is positive, q3 … WebbThe positively charged protons in the nucleus attract the negatively charged electrons. As the number of protons in the nucleus increases, the electronegativity or attraction will increase. Therefore electronegativity increases from …
Webb29 dec. 2014 · When objects A and B are brought together, they attract. When objects B and C are brought together, they repel. From this, we conclude that: (a) objects A and C … WebbSo for spin 0 you get a −: like charges attract. For spin 1 you get a +: like charges repel! And for spin 2 you get a − again: like charges attract. Now for gravity the "charge" is usually called mass, and all masses are positive. So you see gravity is universally attractive!

Verified by Toppr. Correct option is A) Similar charges repel each other whereas opposite charges attract each other. There are 2 types of electrical charges - positive …
WebbSubsequently a unit of charge will attract a unit of charge with significantly more force than a unit of mass will attract a unit of mass. Second, gravitational forces are only attractive; electrical forces can be either attractive or repulsive.
WebbCorrect option is C) Two point charge placed at a certain distance =r force =F dielectric constant =k Let, two point charges q 1 and q 2 are separated r distance from each other. Then, force experienced between then, F= 4πϵ 0r 2q 1q 2 Put, F= 4πϵ 0r 2q 1q 2 ∴ 4πϵ 0r 24q 1q 2= k(4πϵ 0r 2)q 1q 2 ⇒ r 21= 4r 2h1 ⇒ r 21= kr 21 alliance for progressWebb12 okt. 2016 · If you got point chargers, then there are no way two electrical chargers with the same sign attract each other. But if you do not have point chargers but charged bodies (I mean that have volume), each body will have both positive and negative chargers, but if the body is not electrically neutral it will have more of one of the two types of charge. alliance fphWebbWe've seen that if two things have the same charge, so they're either both positive, or they are both negative, then they are going to repel each other. So in either of these cases … alliance forte da casa nifWebbWhich of the following statements about electric charges is true? A) Electrical forces act at a distance. B) Objects must be touching one another to exert electrical force. C) Air cannot conduct electricity, it is conducted only by solid materials. D) Opposite electric charges always repel one another. A. alliance fpsWebb24 dec. 2013 · Two charged objects will attract each other only if they have opposite kinds of charge. If they both have the same kind, then they repel each other. What kind of … alliance francaise chengduBecause charged objects interact with their surroundings, an observed interaction provides possible evidence that an object is charged. Suppose that you enter the physics classroom and observe two balloons suspended from the ceiling.
