An aircraft, flying underneath a negatively charged thunder cloud is induced with positive charges. Which side of the aircraft becomes negatively charged?

Open in App

Solution

Explanation:
Aircraft is made up of conducting material, so the electrostatic charge will get induced on the surface of the aircraft.
When an aircraft passes below the negatively charged cloud, due to the force of repulsion of negative charge from the cloud, the electrons on the surface of the aircraft shift away from the surface and leave the surface positively charged.
Due to the movement of electrons, the surface of the aircraft becomes positively charged while the bottom of the aircraft becomes negatively charged.
