Want this question answered?
On earth, any vertical force greater than 661.39 pounds will lift a mass of 300 kg.
Well, if the Upthrust were greater than the weight, there would be a net force upwards, and as a consequence of newtons second law a=F/m it accelerates upwards. Hence, the submarine floats.
Neither is greater.

In weight, 1.2kg is much heavier than 285g
(Airplane is descending)
It takes off
If lift is greater than weight, the airplane proceeds up, away from the ground. If lift is less than weight, the airplane proceeds down, toward the ground.
The four basic forces acting on an aircraft are Lift, Weight (Gravity), Thrust, and Drag. In order for an aircraft to ascend, Lift must be greater than Weight, and Thrust must be greater than Drag.
The lift produced by the wings is greater than the weight.
If the force is not greater than the weight of the bale, the bale will not move.
Any force greater than its weight.
To lift the baloon, upthrust should be greater than weight. Mg
It sinks
If the buoyant force is greater than the weight of an object than the object will accelerate (assuming there are no other forces acting on the object)
you gain weight
The object sinks.
