Two charges are placed at the corners of an equilateral triangle that is 0.25 m on each side. The first charge is 4.5 µC and the second is 3.2 µC. If a charge if 2.5 µC is placed at the third corner of the triangle, what is the magnitude of the electric force on the third charge due to the first two charges? C 2.5MC.
An atomic nucleus contains positively charged protons and uncharged neutrons. Since nuclei do stay together, what must we conclude about the forces between these nuclear particles? The Force holding them together must be extremely large & strong, and we are correct in that assumption, as the strongest fundamental Force in nature is unown as the strong wuclear force and it the sane one thats holding the meters together actual answer: the force holding the nucleus together must be greater than the 3. Two bodies attract each other electrically. electrostatic repulsive force on the protons. a. Do they both have to be charged? No (It could be through polarization which requires only one of them to be charged) b. Do they both have to be charged if the bodies repel one another.
If q is repelled by the plate, is the plate necessarily charged? yes, since polarization charge would produce only an attractive force. or by using another rod. 5. How would you determine whether the charge on a particular rod is positive, negative or neutral? you can bring it near a charged electroscope. If the leaves diverge, then the rod has the same charge as the electroscope. If the leaus come closer bogether, the rod has an opposite charge to that of the electroscope. If nothing happens then the rod is neutral.
