If an object has a mass of 20 kg, what is the force of gravity acting on it on earth? A. 32.67 N B. 2.04 kg C. 1.96 kg D. 196 N
Answer:
D. 196 N
Explanation:
The force of gravity acting on an object located at the Earth's surface is given by:
\(F=mg\)
where
m is the mass of the object
g is the acceleration due to gravity
In this problem:
- m=20 kg is the mass of the object
- g = 9.81 m/s^2 is the acceleration due to gravity at Earth's surface
Substituting these data into the formula, we get
\(F=(20 kg)(9.81 m/s^2)=196.2 N \sim 196 N\)
