How will the spheres be charged, if at all? 6T, When a negatively charged rod is brought near, but does not touch, the initially uncharged electroscope shown above, the leaves spring apart (I). A positively charged rod is brought near sphere A as suggested in the figure. D NEET Year Wise Previous Years Questions - ExamSIDE.Com DPP 02 1 PDF | PDF | Electric Charge | Electron - Scribd Which of the following describes the resulting charge on the sphere? What is the spring constant of either one of the two half springs? 4: Charging by induction, using a ground connection. 1. A negatively charged rod is brought close to the sphere but does not touch the sphere. 1 and 2 only Charges on the two spheres are q 1 and q 2, respectively. A The three charged +Q, +Q, and -2Q form an electrically neutral system called an electric quadrupole. 8 m/s2 4T Assuming no losses to friction, how high does it get before it stops? E) It is constant between the plates except near the edges. 4 T, A circular ring made of an insulating material is cut in half. zero. It comes to a hill and starts going up. 0000004250 00000 n 0000002579 00000 n If the density of the material of the sphere is 1.6 g c m 3, the dielectric constant of the liquid is: A. trailer << /Size 438 /Info 391 0 R /Root 406 0 R /Prev 424702 /ID[<552265619177062a546f44ebb81a717e><552265619177062a546f44ebb81a717e>] >> startxref 0 %%EOF 406 0 obj << /Type /Catalog /Pages 390 0 R >> endobj 436 0 obj << /S 1678 /Filter /FlateDecode /Length 437 0 R >> stream My first thought upon reading your suggestion starts with taking, 2021 Physics Forums, All Rights Reserved, Which I know is wrong because, in that case, the, Angle between 2 charged spheres hanging from string. Consider Earth to be stationary, and the moon as orbiting Earth in a circle of radius R.
