When a body is earth connected, electrons from the earth flow into the body. This means the body is…..
Unchanged
Charged positively
Charged negatively
An insulator
From what the name electricity is coined ? Explain its meaning.
How can object be charged with contact ?
It is now believed that protons and neutrons (which constitute nuclei of ordinary matter) are themselves built out of more elementary units called quarks. A proton and a neutron consist of three quarks each. Two types of quarks, the so called 'up' quark (denoted by $u$) of charge $+(2 / 3) e,$ and the 'down' quark (denoted by $d$) of charge $(-1 / 3) e$ together with electrons build up ordinary matter. (Quarks of other types have also been found which give rise to different unusual varieties of matter.) Suggest a possible quark composition of a proton and neutron.
Why does matter obtain electric charge ?
The number of electrons in $1.6\, C$ charge will be
