Question

During a jump from the aeroplane at a particular velocity, the air drag on parachute becomes:

• A. equal to the weight of the jumper
• B. less than the weight of the jumper
• C. greater than the weight of the jumper
• D. equal to the weight of the parachute

Answer 1

The correct option is A

equal to the weight of the jumper

During a jump from the airplane, at a particular velocity, the air drag on parachute becomes equal to the weight of the jumper. The air drag plays an important role in maintaining the acceleration of a jumper. The net force is in the downward direction due to the gravity of the Earth.
