You are given the following electric field distribution in s
You are given the following electric field distribution in sphere space (x, p1g, a, b, c are given a, b and c are in meters) E in v/m = 0 r
Solution
(a) at r=a
LHS= left hand limit= limi h-->0 E(a-h)= 0
RHS = right hand limit
= limit h-->0. E(a+h)
= x/(4*epsilon*a^2)
As LHS= RHS
Hence Electric field is not defined at r=a. Or Electric filed is discontinuous at at r=a.
At r=c
LHS= left hand limit
=limit h-->0 E(c-h)
= x/(4*epsilon*c^2)+(c^3-b^3)*p1/(3*epsilon*c^2)
RHS = right hand limit
=limit h-->0 E(c+h)
= x/(4*epsilon*c^2)+(c^3-b^3)*p1/(3*epsilon*c^2)
As RHS= LHS , hence
E(r=c)=x/(4*epsilon*c^2)+(c^3-b^3)*p1/(3*epsilon*c^2)
(b) unit of x= coulomb
Unit of p1=charge density=coulomb/m^3
(C) q=charge
= x, r<a
= 0, a<r<b
=4* p1(c^3-b^3)/3, b<r<c ,
= 0 , c<r<d
= 9, r>d
Cd=Charge distribution
=x/(4a^3), coulomb per unit volume, r<a
= p1 coulomb per unit volume, b<r<c ,
= 0 , c<r<d,
=9/(4d^2) coulomb Per unit area, r>d
