Answer 2

D. 48 N down

Step-by-step explanation:

Given that:

Mass of climber = 85 kg, Tension on rope = 785 N, acceleration due to gravity = 9.8 m/s²

To calculate the net force on the climber, we need to first calculate the weight of the climber. Since the climber is affected by the earth gravity, the weight of the climber is the product of his mass and the acceleration due to gravity, therefore:

Weight = mass × acceleration due to gravity = 85 kg × 9.8 m/s² = 833 N

The weight of the climber is acting downwards while tension on the rope is acting upwards, therefore:

Net force on the climber = 785 N - 833 N = - 48 N

This means that the net force on the climber is 48 N downwards
