#### The spring balance is graduated at sea level. If the body is weighed by this spring scale at gradually increasing heights from the earth's surface,then the weight indicated by the spring scale Option: 1 It will increase continuously    Option: 2 It will decrease continuously    Option: 3 Remains the same    Option: 4 It first increases and then decreases

The weight indicated by the spring scale will decrease continuously as the body is weighed at progressively increasing heights from the earth's surface.

The value of gravitational acceleration (g) decreases as we move away from the earth's surface. As a body is weighted at an increasing height, the distance between the body and the centre of the Earth increases and therefore the gravitational force acting on the body decreases.

A spring balance measures the force exerted by the body on it, which is equal to the weight of the body. As the gravitational force acting on the body decreases, so does the weight indicated by the spring balance.

The correct answer is therefore option (2) - the weight indicated by the spring scale will decrease continuously as the body is weighed at progressively increasing heights from the earth's surface.
