I assume that the ball is stationary (v=0) at point B, so its total energy is just potential energy, and it is equal to 7.35 J.
At point A, all this energy has converted into kinetic energy, which is:
And since K=7.35 J, we can find the velocity, v:

Answer:
The magnitude of the force is 34.59 N.
Explanation:
Given that,
Inside pressure
Area
Outside pressure = 1 atm
We need to calculate the magnitude of the force
Using formula of force
Where, =inside Pressure
=outside Pressure
A = area
Put the value into the formula
Hence, The magnitude of the force is 34.59 N.
