What does the symbol omega mean in physics?
1 answer:
Generally, the symbol 
is used to indicate the angular velocity.
In a circular motion, the angular velocity is defined as the time rate of change of the angular displacement, relative to the origin. If we call
the angular displacement of an object relative to the origin, and t the time, the angular velocity can be written as
and it is measured in radiants per second (rad/s).

Answer:
q = 3.6 10⁵ C
Explanation:
To solve this exercise, let's use one of the consequences of Gauss's law, that all the charge on a body can be considered at its center, therefore we calculate the electric field on the surface of a sphere with the radius of the Earth
r = 6 , 37 106 m
E = k q / r²
q = E r² / k
q =
q = 4.5 10⁵ C
Now let's calculate the charge on the planet with E = 222 N / c and radius
r = 0.6 r_ Earth
r = 0.6 6.37 10⁶ = 3.822 10⁶ m
E = k q / r²
q = E r² / k
q =
q = 3.6 10⁵ C
