Question

a raindrop falls close to a building. what is the correct relationship of forces acting between the raindrop and the building?

Explanation:

Step1: Recall gravitational and electrostatic forces

Gravity acts vertically downwards on the raindrop. There is no significant electrostatic or other non - contact force between raindrop and building in normal conditions. There is no horizontal contact force as well.

Answer:

There is no significant force acting between the raindrop and the building horizontally, and the only significant force on the raindrop is the gravitational force acting downwards. So, if we consider the forces in the context of the given problem and the options (not fully visible but based on the principle), the main force on raindrop is gravity and no force between raindrop and building in normal situation.
