2300 N upward
Explanation:
The force by weight of balloon = 1000 N
The atmospheric force experienced by balloon = 3300 N
While weight of balloon is attracted by gravity so the force of weight will act downward
And the atmospheric force gives upward lifting force to the balloon
Net force = atmospheric force - weight of balloon
= 3300 - 1000
= 2300 N
As the atmospheric force is more dominating the balloon will goes upward with 2300 N force
