Question

The weight of the body at earth's surface is W . At a depth half way to the centre of earth its weight will be (Density Uniform)\

Professor PC Thomas Classes · Answer

$\mathrm{W}=\mathrm{mg}$ $$ \begin{array}{ll} \mathrm{W}^{1}=\mathrm{mg}^{1} & \ \frac{\mathrm{~W}^{1}}{\mathrm{~W}}=\frac{\mathrm{g}^{1}}{\mathrm{~g}} & 	ext { But } \mathrm{g}^{1}=\frac{8}{2} \ 	herefore \frac{\mathrm{~W}^{1}}{\mathrm{~W}}=\frac{1}{2} & \mathrm{~W}^{1}=\frac{\mathrm{W}}{2} \end{array} $$
