The figure given below shows the direction of the two forces PP and QQ acting on a skydiver :

Figure for Q125

Which one among the following statements is correct about the two forces ?

  1. (a) Force PP is caused by the gravity and force QQ is caused by the friction
  2. (b) When the force PP is bigger than the force QQ, the speed of the skydiver remains the same
  3. (c) After the parachute opens, force PP remains the same while force QQ increases
  4. (d) After the parachute opens, force PP decreases while force QQ increases

Solution.

Not scored: no correct option as printed.

Answer: not scored. No option is correct as printed.

  1. P is the downward weight and Q is the upward air resistance, so (a) is true.
  2. Immediately after the parachute opens, weight is essentially unchanged while drag increases, making (c) true as well.
  3. The resulting upward net force slows the downward motion.
  4. The printed single-answer instruction therefore conflicts with two correct statements.
