Question

a pair of closely spaced electron and proton behaves like an electrically neutral particle system and do not apply electric force on isolated proton or electron. give reason..????​

Answer 1

Answer:

wo types of charges exist in nature which are opposite to each other in polarity.These two types of charges have a tendency to cancel the electrical effect of each other. Benjamin Franklin suggested the use of positive and negative signs to represent these two types of charges we can calculate the net charge of any system by evaluating the the algebraic sum of individual charges.

Answer 2

The charged particles of which we are composed are balanced: each positive charge is balanced by a negative charge, so that overall we are electrically neutral. Any imbalance in electrical charge is quickly rectified by picking up charge from something else; that's the reason that we get little shocks in dry weather or in the winter. See the next exercise.
