Two spheres of the same radius, but of different masses, are both fully submerged in water. The lighter sphere is held below the water line by a rope anchored to the bottom of the container. The heavier sphere is suspended from a rope. Which one experiences the larger buoyancy force magnitude?

The lighter sphere held below the water line by a rope anchored to the bottom of the container

Explanation:

Buoyancy is the upward force exerted on an object when it is immersed, partially or fully, in a fluid - and strictly where the fluid is subjected to a gravitational force but is not in free fall - and its value is equal to.

The force of buoyancy will be greater because tension force acting upwards assist the buoyancy force to move it upwards.

acceleration = (change in speed) / (time for the change)

change in speed = (20-120)= -100 m/s.

1.5 min = 90 sec

acceleration = -100/90 = -1.11 m/s^2.

we don't care about the 150kg or the 2,500 meters. they don't make any difference.
