An object of mass 100 kg falls from point $A$ to $B$ as shown in figure. The change in its weight, corrected to the nearest integer is ( $R_{E}$ is the radius of the earth)

Options:

Answer:

Solution:

$M g^{'} = M g \frac{R ^{2}}{( R + h ) ^{2}}$ At A $M g^{'} = M g \frac{R ^{2}}{( R + 2 R ) ^{2}} = \frac{M g}{9}$ At $B M g^{'} = M g \frac{R}{( R + \frac{3 R}{2} ) ^{2}} = \frac{M g \cdot 4}{25}$ Change in weight $= M g \frac{4}{25} - \frac{M g}{9} = 49 N$
