Answer 2

To determine the tension force in the rope, we can use Newton's second law of motion, which states that the net force acting on an object is equal to the mass of the object multiplied by its acceleration. In this case, the net force is the tension force in the rope, the mass is 10 kg, and the acceleration is 2 m/s^2.

Calculation:

Using Newton's second law: net force = mass x acceleration

Given: - Mass (m) = 10 kg - Acceleration (a) = 2 m/s^2

Substituting the given values into the equation, we get: net force = 10 kg x 2 m/s^2 = 20 N

Therefore, the tension force in the rope is 20 Newtons.

Please note that this calculation assumes that the rope is massless and there are no other forces acting on the system except for the tension force and the weight of the object.
