1. In what way pressure and fluid change with the depth?
2. what will happen if two people are appling force in same direction?
Hi Sushmita!
The pressure of a fluid increases with depth.
When two people apply force in the same direction, the forces adds up. The resultant force will be the sum of both the forces. This is similar to two people pushing a car in the same direction, to start it.
Cheers!!
