The fig. shows the motion of a planet around the un in an elliptical orbit with sun at the focus. The shaded areas can be assumed to be equal. If $t_1$ and $t_2$ represent the time taken for the planet to move from $A$ to $B$ and $C$ to $D$ respectively, then
$t_1 < t_2$
$t_1 > t_2$
$t_1 = t_2$
None of the above
If satellite is shifted towards the earth. Then time period of satellite will be
What does not change in the field of central force
Explain Kepler’s first (Law of Orbits) law for planetary motion.
The time period of a satellite of earth is $5$ hours. If the separation between the earth and the satellite is increased to four times the previous value, the new time period will become ......... $hours$
