Passengers in an aircraft are subject to the Normal and Gravity Force acting on them at a low 'orbit', so tiny that it can be many times compared to the same surface of the earth when speaking in general terms.
In a high orbit space vehicle or in the same space, said force decreases considerably or simply disappears, generating the sensation of weightlessness.
Remember that the Force of Gravity is given under the principle
Where,
G = Gravitational Universal constant
M = Mass of the planet
m = mass of the object
r = Distance from center of the planet
When the radius grows considerably the gravitational force begins to decrease.
Answer:
Explanation:
Given
side of square shape
Electric flux
Permittivity of free space
Flux is given by
where E=electric field strength
A=area
=Angle between Electric field and area vector
and Electric field by a uniformly charged sheet is given by
where =charge density
