###### Question:

Its a two parter I think since he lumped them together.

1)

A point charge is located at the center of two thin, concentric, non-conducting spherical shells (both charged). The flux through a gaussian sphere of varying radii (centered at point P) is as follows:

Φ e =1.88 x 106 Nm2/C (for r < r1);

= -2.1 x 106 Nm2/C (for r1 < r < r2);

= 3.3 x 106 Nm2/C (for r > r2).

What is the charge at point P? Give your answer in µC but enter only the numerical part.

2)

A point charge is located at the center of two thin, concentric, non-conducting spherical shells (both charged). The flux through a gaussian sphere of varying radii (centered at point P) is as follows:

Φ e =1.4 x 106 Nm2/C (for r < r1);

= -1.5 x 106 Nm2/C (for r1 < r < r2);

= 4.3 x 106 Nm2/C (for r > r2).

What is the charge on shell 2? Give your answer in µC but enter only the numerical part.
