(a) How many electorns are in 1C of negative charge?
(b) Which is the true test of electrification: attraction or repulsion?
(c ) Can a body have a charge of `0.8xx10^(-19)C` ?

Text Solution

Verified by Experts

(a) `q="ne"`
`n=(q)/(e )=(1)/(1.6xx10^(-19))=6.25xx10^(18)`
(b) Repulsion. As charged body can attarct uncharged body.
(c ) No, as charge is quantized.
