The sphere has a net uniform charge qi +6.36 fic; the shell has a net charge qz --on. What is the magnitude of the electric field at radial distances (a) r 0 am, (b) r- a/2.00, (c) r- a, (d) r 1.50a, (e) r a 2.30a, r-3.50a? what is the net charge on the (g) inner and (h) outer surface of the shell? and (f) teem (a) Number (b) Number (c) Number (d) Number (e) Number (f) Number (9) Number (h) Number click if you would like to show work for this question:Explanation / Answer
given
a = 2.5 cm = 0.025 m
b = 2 a = 5 cm = 0.05 m ,
c = 2.4 a = 4.8 cm = 0 .048 m
q1 = 6.36 fC , q2 = - q1
a )
When r = 0 then q = 0
then E = 0
b )
E = 9 X 109 X q r / a3
r = a/2
E = 9 X 109 X q r / a3
E = 9 X 109 X 6.36 X 10-15 X (a/2 ) / a3
E = 9 X 109 X 6.36 X 10-15 / 2 a2
E = 9 X 109 X 6.36 X 10-15 / 2 X 0.0252
E = 0.0457 N/C
c )
r = a
E = 9 X 109 X q X a / a3
E = 9 X 109 X q / a2
E = 9 X 109 X 6.36 X 10-15 / 0.0252
E = 0.091584 N/C
d )
E = 9 X 109 X q / (1.52 X a2 )
E = 9 X 109 X 6.36 X 10-15 / 1.5 X 1.5 X 0.0252
E = 0.0407 N/C
e )
R = 2.3 a
b < r < c
E = 0
f )
R = 3.5 a
4 X 3.14 X r2 X E = 0
E = 0
g )
q2 = - q1
q2 = - 6.36 X 10-15 C
h )
q2 = - q1
qo = 0
