    Solution:

    The weight of a 70 kg man on the moon will be 112 N. The weight of an object is the force exerted by the mass of the object under the influence of gravitational force.
    According to the question,
    The mass (m) of a man on the moon is 70 Kg
    The acceleration due to the gravity on the moon is gm=1.6m/s2 We know that Weight of object on moon(W)=m×gm
                                                                                 W=70×1.6
                                                                                      W=112N
    That means a man would weigh 112 N on the moon.
    Here, always remember that the mass of a body is constant throughout the universe. As a result, the mass of this man would have been the same on Earth and on the Moon, i.e. 70 kg on Earth and 70 kg on the Moon.
