Positive, Negative, Negative<\/span><\/span><\/p>\nD. Positive, Negative, Positive<\/span><\/span><\/p>\nSolution :<\/span><\/span><\/p>\nThe electric charge consists of two types: positive electric charge and negative electric charge<\/span><\/span><\/span>. Each type of charge repels the same type but attracts the opposite type. That is: unlike charges attract; like charges repel.<\/span><\/span><\/p>\nIf charge A is a positive charge, charge A repels charge B, then the charge B is a positive charge. If charge P is a negative charge, charge P attract charge Q, then the charge Q is a positive charge.<\/span><\/span><\/p>\nA is a negative charge.<\/u><\/span><\/span><\/p>\nD is a negative charge.<\/u><\/span><\/span><\/p>\nA attract <\/span><\/span>B so that <\/span><\/span>B is a positive charge<\/u><\/span><\/span>.<\/span><\/span><\/p>\nA repels C so that <\/span><\/span>C is a negative charge<\/u><\/span><\/span>.<\/span><\/span><\/p>\nD repels E so that <\/span><\/span>E is a negative charge<\/u><\/span><\/span>.<\/span><\/span><\/p>\nTypes of charges B, C, and E is positive, negative, negative.<\/span><\/span><\/p>\nThe correct answer is C.<\/span><\/span><\/p>\n<\/p>\n
2.<\/span><\/span><\/p>\nIf the glass is rubbed with a silk, the correct explanation in the following table is \u2026<\/span><\/span><\/span><\/p>\n![\"Types](\"https:\/\/gurumuda.net\/physics\/wp-content\/uploads\/2018\/05\/Types-of-electric-charges-\u2013-problems-and-solutions-10-300x170.png\")
<\/p>\n
Solution<\/span><\/span><\/p>\nGlass has a positive charge, so if the glass is rubbed with a silk cloth then the electrons move from the glass to the silk, so the glass has more protons than the electrons.<\/span><\/span><\/p>\nProtons are positively charged therefore glass becomes positively charged. Instead, silk has more electrons than protons. The electrons are negatively charged so that the silk fabric becomes negatively charged.<\/span><\/span><\/span><\/p>\nThe correct answer is A.<\/span><\/span><\/p>\n<\/p>\n
3. <\/span><\/span>Plastic rod rubbed with wool<\/span><\/span><\/span>, <\/span><\/span>the correct explanation is…..<\/span><\/span><\/span><\/p>\nA. E<\/span><\/span>lectrons in the wool move to plastic, plastic negatively charged <\/span><\/span><\/span><\/p>\nB. E<\/span><\/span>lectrons in the plastic move to wool, wool negatively charged <\/span><\/span><\/span><\/p>\nC. E<\/span><\/span>lectrons in the wool move to plastic exchanging with protons, wool negatively charged <\/span><\/span><\/span><\/p>\nD. E<\/span><\/span>lectrons in the plastic move to wool and exchange with protons, plastics positively charged <\/span><\/span><\/span><\/p>\nSolution :<\/span><\/span><\/p>\nThe electrical charge on plastics is internationally agreed as a negative charge.![\"Types](\"https:\/\/gurumuda.net\/physics\/wp-content\/uploads\/2018\/05\/Types-of-electric-charge-3.png\")
\nPlastic or any object becomes negatively charged due to excessive electrons. Because the plastic is rubbed with wool it is concluded that electrons move from wool to plastic.<\/span><\/span><\/span><\/p>\nThe correct answer is A.<\/span><\/span><\/p>\n4. There is a ball P conductor with negatively charged and four balls of Q, R, S, T.<\/span><\/span><\/p>\n![\"Types](\"https:\/\/gurumuda.net\/physics\/wp-content\/uploads\/2018\/05\/Types-of-electric-charge-4.png\")
