Answer:
Step-by-step explanation:
When a thundercloud becomes charged, it induces an opposite charge in objects on the ground below it through a process called induction.
The negative charges within the thundercloud repel the electrons in the objects on the ground, causing the electrons to move away, leaving the area beneath the cloud with a relatively positive charge. This movement of electrons creates an imbalance of charges, where the positive charges are left behind in the objects or surfaces underneath the cloud.
In the case of the tree below the thundercloud, the positive charges gather on the tree's surface, creating a positive charge on the tree itself. This positive charge is induced by the negative charge in the thundercloud and the redistribution of electrons within the tree.
