Which force puts an object into free fall?

Gravity

Explanation:

When we say that object is in free fall then it always means that the object will move under the influence of gravitational force only

So here we can say that

under free fall condition the force on the object is given as

so the acceleration of free fall is always constant and given as

so correct answer is

Gravity

force is mass*acceleration.

we have a very small mass: 11.4*0.001 kg

if we want 0.035n of force, we need an acceleration:

0.035 = 11.4*0.001*a

a = 0.035/(11.4*0.001) m/s^2
