Vedclass · Answer

(A) According to the law of conservation of angular momentum,the angular momentum of the satellite remains constant throughout its orbit.At the closest point (periapsis) and farthest point (apoapsis),the velocity vector is perpendicular to the position vector.Therefore,$L = m r_{\min} V_{\max} = m r_{\max} V_{\min}$.This simplifies to $r_{\min} V_{\max} = r_{\max} V_{\min} \quad \dots(i)$.Given that the velocity at the farthest point is $6$ times less than the velocity at the closest point,we have $V_{\min} = \frac{V_{\max}}{6}$,or $\frac{V_{\min}}{V_{\max}} = \frac{1}{6}$.Substituting this into equation $(i)$,we get $\frac{r_{\min}}{r_{\max}} = \frac{V_{\min}}{V_{\max}} = \frac{1}{6}$.Thus,the ratio of the distances is $1:6$.

Which of the following graphs represents the relationship between the orbital velocity $(v_o)$ of a satellite and its distance $(r)$ from the center of the Earth?

The orbital angular momentum of a satellite is $L$,when it is revolving in a circular orbit at height $h$ from the earth's surface. If the distance of the satellite from the earth's centre is increased by eight times its initial value,then the new angular momentum will be $............\,L$.
