Welcome to this IE. You may navigate to any page youve seen already using the IE tab on the right. Spherical Shell Insulator 0 t P An insulator in the shape of a spherical shell is shown in cross-section above. The insulator is defined by an inner radius a-4 and an outer radius b-6cm and carries a total charge of Q.+9pC(1 μC . 106 C), oou may assume that the charge is distributed uniformly throughout the volume of the insulator). What is Ey, the y-component of the electric field at point P which is located at (x,y)- (0, -5 cm) as shown in the diagram? N/C Submit

Answer 1

Given is:-

Now,

The volume of the insulator is given by

or

and the volume of the insulator till the point P is

Volume charge density is

Now,

the charge enclosed by the region P is

by plugging all the values and simplifying we get

Now,

According to the Gauss's law

or

by plugging all the values we get

which gives us

The charge is uniformly distributed and positive. The field is radially outward. The electric field at (0cm , -5cm) is

E =-1.3 × 10% Ņ/C
