which of the four forces makes paint cling to a wall ?which force makes adhesive sticky?which force makes wax to stick a car ?
True [87]

Answer:

This question is incomplete

Explanation:

The question is incomplete because of the absence of options.

However, <u>the force that makes a paint cling to a wall is adhesive force</u>. Adhesive force is the force between two unlike substances like a liquid clinging to a solid surface.

The force between adhesives or glue is also the force that makes them sticky. <u>This force is referred to as cohesive force</u>. This is a force found in between similar molecules (unlike adhesive force found between dissimilar molecules).

<u>The force that makes wax to stick to a car is electromagnetic force</u>. This is a force between charged particles; whether they appear to be moving or not. These particles of opposite charges come together to form a neutral force. In this case, charged atoms of the car and the wax come together (which causes what we see as the wax sticking to the car).
