Sir, Koi bhi body positively ya negatively charged hai kaise pata chalega?

[@rahulkargwal7064]

Agar koi body electron deti h to vo positively charge ho jawgi

[@anubhavswami7261]

But practically kaise pata chalega ki body ne electron free kar diya?

@@anubhavswami7261 bari bari se positively charged body and negatively charged body ke pass lakar..

[@anubhavswami7261]

@@SURAJ_ASSAM To wo positively charged body जिसे पास लाने की baat कर रहे हो... kaise pata chla ki ei positively charged है... practicals के base पर batao.. theory to mujhe bhi pata hai

@@anubhavswami7261 When you rub two different materials together, the friction between them produces a positive charge in one and a negative charge in the other. To determine whether one of them has a positive or negative charge, you can refer to a triboelectric series, which is a list of known materials sorted by increasing negative charge. Rubber, for example, is lower on the list than wool, so stroking rubber with wool will reliably create a negative charge in the rubber. Knowing this, and armed with an electroscope for measuring charge, you can determine whether the charge of an object is positive or negative......,,🙂
