How do you find the strength and direction of the net force on an apple weighing 2n neglecting air resistance when the apple held in the hand falls to the ground and when the apple moves upward?

Apple held in hand.
According to Newton's First Law, It is at rest, thus there is no net force.
srength of resultant force = 0N
Apple falling to the ground.
According to Newton's Second law,
The object will accelerate in the direction of force applied. Hence its downwards.
Strength of resultant force = 2N
Apple moving upwards.
According to Newtons Second law,
(same as above) upwards.
Strength undefined.

What is air resistance reduced by?
Air resistance is reduced by reducing the surface area of an object facing the air flow, making it more streamlined. Additionally, objects with smooth surfaces experience less air resistance compared to objects with rough surfaces. Increasing the velocity of the object can also help in reducing air resistance.
Why will a rock and feather land on the ground at the same time?
They won't. Two nearly identical objects (equal-sized cubes for example) will land at the same time as long as they are heavy enough to overcome wind resistance. If you have a ten-pound ball and a twenty-pound ball, they will hit the ground at the same time. However, if you had a ball weighing less than an ounce and one weighing a pound, of course they will not hit the ground at the same time: the ball weighing less than an ounce wouldn't fall - it would be affected enough by wind resistance to slow down. If there was no air, the feather and the rock will hit the ground at the same time. Factoid.
Steps for weighing an object?
Obtain an appropriate weighing device. Make sure the device is calibrated properly. Perform the weighing by placing the object on top of the weighing device.

Which ball would reach the ground first one weighing one half kg or one weighing 1 kg?
If dropped from the same height, they both will reach the ground at the same time. The acceleration of gravity is the same for all objects regardless of mass. The only thing that would change this would be air resistance on the balls, which is assumed to be negligible for objects of comparable sizes.
Why the sodium hydroxide is weighing in a weighing bottle and not on a piece of filter paper?
Because sodium hydroxide is deliquescence and will absorb carbon dioxide from the air if exposed to it, therefore the weighing is performed in weighing bottles and not in the open, like on a piece of paper.
