L'=mv'r'=m(√(G M/2 r))(.2r.) <img class="img-fluid question-image" alt="Solution" src="https://cdn.tardigrade.in/q/nta/p-qskhqhehnsbkjjxp.jpg" /> =√2mvr=√2L

Q. A satellite is in a circular equatorial orbit of radius $7000 km$ around the Earth. If it is transferred to a circular orbit of double the radius then its angular momentum will be :-

Increases

Decreases

Remain unchanged

None of these

$L^{'} = m v^{'} r^{'} = m (\frac{GM}{2 r}) (2 r)$

$= 2 m v r = 2 L$
