As is known, all mater is made up of atoms/molecules. Every atom consits of a central of a central core, called the atomic nucleus, around which negatvely charged electrons revole in ciruclar orbits. Every atom is electrically neutral. Containing as many electron as the number of protons in the nucleas.
Thus, even though normally, the materails are electrically neutral, they do contains charges, but thier charges are exactly balanced. The vast amount of charge in an object is usually hidden as the object is usually hidden as the object is said to be electracally neutral charge. With such an equality or balance of charges the object is said to be electrically neutral or uncharged. To electrify or charge a neutral body, actully transfer to the other body. The body which gains electrons become negatively charged and the body which loses electrons becomes positivelyh charged. Further, like charges repel adn unlike charges attract.
Read the above passage and answer the following questions :
(i) Every body, whether a conductor or an insulator is electrically neutral. Is it true ?
(ii) Charging lies in charge imbalance, i.e, excess charge, comment.
(iii) How do you visualize this principle being applied in our daily life ?

Text Solution

Verified by Experts

(i) Yes, it is true. Every conductor/inssularor is elecrtrically neutral, as it contains equal amounts of positive charge and negative charge.
(ii) This statement is true. Charging lies really in charge imbalance. When a body loses some electrons, it becomes positively charged because it has excess of protons over electrons. The reverse is also true.
(iii) Nature/God has created the universse. In original,all bodies are neutral with no forces fo attraction/repuslsion. When intersts of any two persons clash (i.e., two bodies are rubbed against eachother), they become charged. From the charging, arise the forces of attractions/repulsion, i.e., pulls and pressures of life.
Nature/God wants us to live in peace without stress and tensions in life. We get charged over petty things in life and invite all sorts of pulls, pressures and tensions.
