Answer:
E = 53.3 N/C
Explanation:
The charge of the sphere can be found by Gauss’ Law:
We will draw an imaginary spherical surface around the original sphere with radius 0.2 cm. The integral in the left-hand side is the area of this surface, therefore no need to take the integral. The right-hand side is equal to the total charge enclosed by this imaginary surface.
Now that we have found the charge of the sphere, we can now apply Gauss’ Law again to find the E-field 0.006 m from the center.
We will draw our second imaginary spherical surface with a radius 0.006 m.

Rise in altitude is directly proportional to decrease in pressure
The earth's atmosphere has its own pressure known as atmospheric pressure.The pressure level is highest right at the surface of the earth because the air at this level is supporting the weight of all the air above it. More weight above means a greater downward gravitational force. As we move up through levels of the atmosphere, the air has less air mass above it and gravity isn’t strong enough to pull down a greater number of particles. So the balancing pressure decreases. This is why atmospheric pressure drops as we rise in altitude.
