Question

list out the required matrial and explain an activity to show that there is no effect of area of contact of the object on frictional force​

Answer 1

1. A block of wood

2. Sand paper

3. Marble

Explanation:

Try sliding the block on sand paper in an inclined plane. Observe that it stops after sometime, on the sand paper itself.

Try the same activity with a marble. You will observe that it keeps moving lot more before coming to stop, as compared to the block.

Trick is,

SURFACE AREA IN CONTACT

Adhesion takes place between two objects in contact during motion, or rest.

it takes place due to frictional forces between two bodies

thus, there is no way that area in contact does not matter.
