Question

3- tiered bithday cake rests on a table. from bottom to top the cake tiers weigh 16, 9, 5 respectively
find the magnitude and direction of normal force acting on 2nd tier?

Answer 1

Gee... this is tough.

Could it be (9+5) and up?

(... suspense is killing me)


Normal force is the one directed perpendicular to the surface.
In this case it is the surface of the second tier. The force is produced by the first tier. So now kidding aside

N= 5
