We can find the weight from the formula:
here, "W" is the weight of the person, "m" is the mass of the person, "g" is the acceleration due to gravity, "G" is the gravitational constant, "M_E" is the mass of the Earth, "r_E" is the radius of the Earth.
Then, we can find the new weight of the person on the Earth which six times as massive as it is and its radius is four times its present value:
Then, we calculate "W_{new}":
Answer:
"W_{new} = 285N."
