when a man travel from hilly region to terai region what will happen to his weight? explain with reason.

His weight increases.

Explanation:

The weight of the body is the gravitational force acting on the body at that location. The gravitational force is defined as the product of mass of the body and the acceleration due to gravity.

W = m x g

The acceleration due to gravity of earth is high at the surface and decreases with respect to the height from the surface. Hence, a man in the higher altitude regions experience lower weight that in the the lower altitude regions.
