Question

Explain why charge given to a hollow conductor is transferred immediately to outer surface of the conductor

Answer 1

In all conductors, charges reside on the surface.

The reason for this is that conductors have free electrons, that is, the electrons are loosely attached to the nucleus of the atoms in the conductors.

Refer to the pic below (drawn in MS Paint)

When placed in external electric field, the electrons migrate to one side of the conductor and an electric field is created inside the conductor itself due to separation of positive and negative charges, as is evident from the pic. In case of conductors, this electric field is equal to that of the external electric field and hence neutralises the external field.

So the net field inside the conductor is zero.

Answer 2

$\huge\bf{hey}$ 

$\huge{ \mathfrak{here \: is \: answer}}$

$\huge{charge}$

▶ 
$\sf{it \: is \: internal \: properties \: of \: some }$
$\sf{elementry \: particle \: for - electron }$
$\sf{proton \alpha \: particles \beta particles \: antipositron \: positron \: }$
$\sf{it \: can \: not \: be \: seen \: but \: it \: can \: be \: feel}$
$\sf{by \: experiment}$

▶ it is a scalar quantity and it is denoted by
'Q' or 'q' .

▶ the main cause of charge developed is friction so charge is also called friction electric.

▶ unit of charge

⭐ si unit - coulomb

⭐cgs or esu - stat coulomb

⭐ mks or Ems - absolute coulomb.

▶ relation between units of charge 

see in pic

▶ conservation of charge

servation theory of charge, charge is neither created nor be destroyed it is only transferred from one body to another body.

this theory age understood by the following given example

nacl

LHS 
total no of charge = 0 

rhs 

total no of charge = 1+(-1)
0

from the both example it is clear that charge is conserved

$\bf{types \: of \: charge}$

✴ positive 

✴ negative

⚫ positive charge: if any substance or element released electron then substance becomes positive charge.

⚫ negative charge : if any neutral element or substance observe or gain electron then substance becomes negatively charged.

✡ quantization theory of charge

according to quantimisation theory of charge excess charge of any body is always defined in the form of integer product of electron
q= ne

now
according to question

it is because the metal have positive charge and have free electrons and also its electrons are loosely bound with nucleus
