Respuesta :
343 N is the gravitational force a 35 kg person standing on the earth's surface exerts on the earth .
Newton's second law is a quantitative description of the changes that a force can produce on the motion of a body. It states that the time rate of change of the momentum of a body is equal in both magnitude and direction to the force imposed on it.
According to Newton's universal law of gravitation, The force of attraction between any two bodies is directly proportional to the product of their masses and is inversely proportional to the square of the distance between them.
According to newtons second law
Force = mass * acceleration
since , we need to find gravitational force so, acceleration will be equal to acceleration due to gravity on earth.
Force = mg
= 35 * 9.8
= 343 N
