An airplane is cruising at an altitude of several kilometers. The pressure outside the craft is 0.258 atm within the passenger c
ompartment the pressure is 1.00 atm and the temperature is 20∘C. The density of air is 1.20 kg/m3 at 20∘C and 1 atm of pressure. A small leak occurs in one of the window seals in the passenger compartment. Model the air as an ideal fluid to find the speed of the stream of air flowing through the leak.

If one of two interacting charges is doubled, the force between the charges will double.
Explanation:
The force between two charges is given by Coulomb's law
K=constant= 9 x 10⁹ N m²/C²
q1= charge on first particle
q2= charge on second particle
r= distance between the two charges
Now if the first charge is doubled,
we get
F'= 2 F
Thus the force gets doubled.
