INATAL Which of the following statements is correct regarding Kepler's three laws of planetary motion? Planets move in elliptical orbits with the sun not being at its center.. Angular momentum of any planet about an axis through the Sun and perpendicular to the orbital plane is not invariant during its motion. Orbital period of a planet is directly proportional to its distance from the sun. Kepler's laws are valid only for planets in the solar system.

Which of the following statements correct regarding Kepler's three laws of planetary motion?
Planets move elliptical orbits with the sun not being at its center.
Angular momentum of any planet about an axis through the Sun and perpendicular to the orbital plane is not invariant
during its motion.
Orbital period of a planet is directly proportional to its distance from the sun.
Kepler's laws are valid only for planets in the solar system.
A block of mass 10 kg is attached to a spring of spring constant 1000 N/m. Block is pulled by 15
cm downwards (Point A) from its equilibrium position and released.
In case 1) block now performs a SHM.
In case 2) spring is cut when it was at its natural length and the block was moving upwards (during
SHM).
Find the difference of time taken by the block reaches to point A in case 1 and case 2. (Take g = 10
m/s/s)
