Can the frictional electricity produced during landing of a plane be used for constructive purposes?

As we know that in aeroplane during landing the charged produced in it due to the friction with ground are earthed through its wheels; can this charge be stored with the help of a capacitor and used

Calculating charge on a body with excess of electrons

How would I calculate the charge on a small sphere with an excess of 5.0 x 10 14 electrons?

Asked Kaitlin Thomas

Answer:

We know that charge on an electron is (-) 1.6 x 10-19 C

If the sphere has 5.0 x 10
