stich3 [128]

C. middle layer, density increases with depth as pressure increases

Explanation:

The mantle is the middle layer of the earth. It's density increases with depth as pressure increases.

  • Based on the compositional division of the earth, our blue planet is divided into crust, mantle and the core.
  • The crust is the lightest and the outermost layer of the earth.
  • The mantle is the middle layer. Its density lies between that of the core and crust.
  • The mantle is the largest layer and density increases with depth here.
  • The core is a metallic ball. It is the most dense part of the earth.

A thin, metallic spherical shell of radius 0.187 m has a total charge of 6.53×10−6 C placed on it. A point charge of 5.15×10−6 C
MAVERICK [17]

Answer: a) 112.88 * 10^3 N/C; b) The electric field point outward from the center of the sphere.

Explanation: In order to solve this problem we have to use the gaussian law so we use a gaussian surface at r=0.965 m and the electric flux is equal to Q inside/εo

E* 4*π*r^2= Q inside/εo

E= k*Q inside/r^2= 9*10^9*(6.53+5.15)μC/(0.965)^2=122.88 * 10 ^3 N/C
