Question

Calculate the force of gravity on earth of an object that has a mass of 200 kg. A. 1,962 N B. 123 N C. 20 N D. 326 N

Answer 1

For this case we have that by definition, the gravity of the earth is given by:

$g = 9.807 \frac {m} {s ^ 2}$

On the other hand, Newton's second law states:

$F = M * g$

Where:

F: It's the force

M: It's the mass

g: Acceleration of gravity

$F = 200 * 9.807\\F = 1961.4 \ N$

Answer:

Option A
