Consider a coin of Question 20 . It is electrically neutral and contains equal amounts of positive and negative charge of magnitude 34.8 kC. Suppose t

Here, `q=+-34.8RC=+-3.48xx10^(4)C` `r_(1)=1cm=10^(-2)m,r_(2)=100m,r_(3)=10^(6)m and (1)/(4piepsi_(0))=9xx10^(9)` `F_(1)=(|q|^(2))/(4piepsi_(0)r_(1)^(2))=(9xx10^(9)(3.48xx10^(4))^(2))/((10^(-2))^(2))=1.09xx10^(23)N` `F_(2)=(|q|^(2))/(4piepsi_(0)r_(2)^(2))=(9xx10^(9)(3.48xx10^(4))^(2))/((100)^(2))=1.09xx10^(15)N` `F_(3)=(|q|^(2))/(4piepsi_(0)r_(3)^(2))=(9xx10^(9)(3.48xx10^(4))^(2))/((10^(6))^(2))=1.09xx10^(7)N` Conclusion from this result we observe that when `+-` charges in ordinary neutral matter are separated as point charges, they exerted an...

Ammonia contains 82.32% of nitrogen and 17.65 % of hydrogen . Water contains 88.90% of oxygen and 11.10% of hydrogen . Nitrogen trioxide contains 63.1

In `NH_(3), 17.65 g` of H combine with N=82.35 g `therefore` 1 g of H combine with H`=(82.35)/(17.65) g` =4.66 g In `H_(2)O, 11.10 g` of H combine with O=88.90...
