Answer:
Option D. 9.8 N
Step-by-step explanation:
From the question given above, the following data were:
Mass of object = 1 kg
Normal force (R) =.?
The normal force experienced by the object can be obtained by using the following formula:
Normal force (R) = mass (m) × acceleration due to gravity (g)
R = mg
Mass of object = 1 kg
Acceleration due to gravity (g) = 9.8 m/s²
Normal force (R) =.?
R = mg
R = 1 × 9.8
R = 9.8 N
Thus, the normal force experienced by the object is 9.8 N
