When a falling object encounters of air resistance, its acceleration is
(a) less than g.
(b) g.
(c) more than g.
(d) Not enough information.
The correct option for the statement " When a 15-N falling object encounters 10-N of air resistance, its acceleration is".
Answer to Problem 7RAT
The correct option for the statement "When a 15-N falling object encounters 10 N of air resistance, its acceleration is" is option (a).
Explanation of Solution
When the body is free fall, the body move downward under the action of gravity On earth, the gravitational acceleration acting on the free-falling object is equal to 9.81 m/s2, and it is denoted by the small letter "g".
But in the given problem, the air resistance also acts on the object in the opposite direction that decreases the value of acceleration acting on the object. Thus, the actual acceleration acting on the object must be lesser than g. From this, it is concluded that option (a) will be correct among the given options.
Conclusion:
Therefore, the correct option for the statement " When a 15-N falling object encounters 10-N of air resistance, its acceleration is" is option (a).
