Determine the force of gravitational attraction between the earth (m = 5.98 x 1024 kg) and a 70-kg physics student if the student is in an airplane at 40000 feet above earth's surface. This would place the student a distance of 6.39 x 106 m from earth's center.

N

Explanation:

From the Question we are told that

Earth mass

Students mass

Distance of student from earth center Radius

Generally the equation for Force of attraction b/w the earth and the boy is mathematically given by

Therefore the force of attraction b/w the student and the earth is

r=rho l/a where a is the area, l is the length and rho is resistivity so the greater the area the lesser the resistance thats why the earth pin is thicker bcos current follow the shortest path, so less resistive .

true is the correct answer
