The Correct Option isD
Solution and Explanation
when packet is released from satellite, it will have the same velocity as satellite say $v _{ p }$ in direction same as satellite.
assume mass of particle is $m$
so centrifugal force on particle $=\frac{m v_{ p }^{2}}{ r }$
and gravitational force acting on particle $=\frac{ mGM _{ e }}{ r ^{2}}$
These forces will get balance accordingly and particle will start revolving around earth as satellite is also revolving, particle will never reach earth.
In mechanics, the universal force of attraction acting between all matter is known as Gravity, also called gravitation, . It is the weakest known force in nature.
Newton’s Law of Gravitation
According to Newton’s law of gravitation, “Every particle in the universe attracts every other particle with a force whose magnitude is,
