Solution

The correct option is D

Angular momentum $L = \sqrt{m^{2} G M r} ∴ L \propto \sqrt{r}$

$\frac{L_{2}}{L_{1}} = \sqrt{\frac{r_{2}}{r_{1}}} = \sqrt{\frac{16 r}{r}} = 4 L_{2} = 4 L_{1} = 4 L$

The correct option is D Angular momentum L=√m2GMr ∴ L∝ √r L2L1=√r2r1=√16rr=4L2=4L1=4L

The correct option is D

Angular momentum $L = \sqrt{m^{2} G M r} ∴ L \propto \sqrt{r}$

$\frac{L_{2}}{L_{1}} = \sqrt{\frac{r_{2}}{r_{1}}} = \sqrt{\frac{16 r}{r}} = 4 L_{2} = 4 L_{1} = 4 L$
