Vedclass · Answer

(B) The weight of a body measured by a spring balance is given by $W = mg$,where $m$ is the mass of the body and $g$ is the acceleration due to gravity.As the height $h$ from the Earth's surface increases,the acceleration due to gravity $g$ decreases according to the formula $g_h = g \left( 1 + \frac{h}{R} \right)^{-2}$,where $R$ is the radius of the Earth.Since $m$ remains constant and $g$ decreases with increasing height,the weight $W$ indicated by the spring balance will go on decreasing continuously.

$A$ spring balance is graduated at sea level. If a body is weighed with this balance at consecutively increasing heights from the Earth's surface,the weight indicated by the balance:
