We know
That a force of gravity acts downward and thus tries to bring the body towards earth. But lift force here will act upward that is in opposite directions of the gravity force.
Also
Force of gravity = 3000 N
And
Lift force = 3300 N
Now,
Newt force = 3300 - 3000
= 300 N ( in upward direction )
Thus the net force will act in upward direction.
Thus last option is correct.

A helium balloon is used to lift a load of 106 N. The weight of the envelope of the balloon is 51.5 N and the volume of the helium when the balloon is fully inflated is 33.9 m3. The temperature of the air is 0°C and the atmospheric pressure is 1.00 atm. The balloon is inflated with a sufficient amount of helium gas that the net upward force on the balloon and its load is 30.6 N. Neglect any effects...

a 3000 N upward tension force is exerted on a 320-kg downward-moving freight elevator. Determine the acceleration of the elevator.
a) Calculate the buoyant force (in N) on a 2.30 L helium balloon. I got .029 N upward for part a but can't seem to figure out part b. b) Given the mass of the rubber in the balloon is 2.00 g, what is the net vertical force (in N) on the balloon if it is let go? You can neglect the volume of the rubber.
When a charged balloon sticks to a wall, the downward gravitational force is balanced by an upward static friction force. The normal force is provided by the electrical attraction between the charged balloon and the equal but oppositely charged polarization induced in the wall's molecules. If the mass of a balloon is 2.1 g, its coefficient of static friction with the wall is 0.70, and the average distance between the opposite charges is 0.80 mm, what minimum amount of charge...
