Question

The electric field inside a spherical shell of uniform surface area

Answer 1

Electric field ( E ) is a characteristics of a space...it is that space when a charge particle enter in it , it experience force , due to which charge particle starts accelerating....

E = kQ / r^2 ---- ( i )
where
k = coulombs constant = 9 × 10 ^9
Q = Source Charge
r = different locations where Efect of E can be experienced

Here , from relation ( i ) , E is directly proportional to Q
=> This means that The source of E is Q...if Q= 0 then E =0 ...

Whenever we give charge inside the shell , due repulsive property...charges repel each other and reach to the surface...all the charges distribute themselves on the surface uniformly so that net force between them is zero...so the charges at rest...Charges cannot move in air further when they reach the surface because the dilectric strength of air is much greater...If the charges anyhow overcome this dilecteic strength then insulation of air got breakdown as a result charge starts flowing in air...

But this generally doesnt happened...to be this happen , it requires lot of potential...

So whenever we charge a spherical shell , all the charges reach the surface due to their repulsive nature and distribute them uniformly....Inside the shell there is no charge i.e , q = 0 ,
So using relation ( i ) , Electeic field inside the shell is zer0....

This can also be proved by Gauss theorem easily as E inside the conducting shell is zero...
