Two objects are placed on a table object one has a mass of 2 kg and a bottom surface area of 0.1m. object to has a mass of 8 kg in the bottom surface area of 0.4 m. how much pressure does each object exerts on the table top.

Pressure exerted by each mass on the surface is given by

here F = force due to weight of object

A = area of the base

now for object 1 we will have

Similarly for object 2

So by the above calculations we can say that pressure at the bottom surface will be same due to both blocks.

i don't know that i agree with that but what's the question ?

true tan speed = ang vel x radius
