The figure given below shows the direction of the two forces P and Q acting on a skydiver : Which one among the following statements is correct about the two forces ?

In the given scenario of a skydiver, Force P (acting downwards) represents Gravity or the weight of the skydiver. Since weight is determined by mass and the acceleration due to gravity (W = mg), it remains constant throughout the descent. Therefore, Force P does not change when the parachute opens.

Force Q (acting upwards) represents Air Resistance (Drag). Air resistance depends on the object's speed and its surface area. When the parachute opens, the effective surface area increases significantly, causing a sudden and large increase in the upward air resistance (Force Q). This increased drag force eventually balances the weight at a much lower terminal velocity, allowing for a safe landing. Thus, Option C is correct because Force P remains the same while Force Q increases due to the increased surface area of the open parachute.
