Question

what is the acceleration produced in a freely falling body of mass 10 kg

Answer 1

Acceleration of any freely falling body is equal to acceleration due to gravity of earth i.e g=9.8m/s2.

It is because acceleration on the body does not depend on its own mass. It depends on the force exerting body. And here the force exerting body is constant i.e earth so acceleration on every free falling body is equal to g.
