Answer:
266.7k
Explanation:
Given parameters:
Initial pressure = 36Pa
Initial temperature = 300k
New pressure = 32Pa
Unknown:
New temperature = ?
Solution:
To solve this problem, we have to apply the combined gas law when the volume is constant;
in this instant, when the volume is constant, the pressure of a given mass of gas varies directly with the absolute temperature.
=
P and T are pressure and temperature
1 and 2 are initial and final states
Insert the parameters and solve;
=
T₂ = 266.7k
To solve this problem we will start by applying the given load ratio, and we will rely on the two types of distances given. Later we will use Gauss's law and through its integrals, in which it is equivalent to the potential we will obtain its value in the center of the sphere. Since it is uniformly charged we have to,
By Gauss Law
Here, E is the electric Field and is equal to
For being the Permeability constant at free space
Replacing with the previous value we have,
Then the value of the electric field is,
Now potential
