The magnitude of that other charge will be 9×10⁻⁵ C. The force on the charge is inverse of the distance.
<h3>What is Columb's law?</h3>The force of attraction between two charges, according to Coulomb's law, is directly proportional to the product of the charges and inversely proportional to the square of the distance between them.
The magnitude of that other charge is found as;
Hence, the magnitude of that other charge will be 9×10⁻⁵ C.

The gravitational potential energy of an object, measured with respect to the ground, is given by
where m is the object's mass, g is the gravitational acceleration and h is the height of the object measured from the ground.
In our problem, the mass of the plane is m= 5 tons = 5000 kg, while the potential energy is
so we can re-arrange the previous formula and use these data to calculate h, the height of the airplane:
