    i think it will move tangentially and then escape away

    the answer to this question is b)move tangentially and escape away. since the velocity of the satellite is always tangent to the path for case c .. somehow the velocity of the satellite have to become zero as well as no gravity then it stops

    if the object is stationary initially, it would fall on earth there and then itself

    for gravity to become 0 suddenly, it has to exist first

    if the satellite has no speed and there is no force (like gravity) acting upon it it stands still.. so for case c to happen you need to have no gravity + zero speed

    we see the transition time, when we say the gravity is becoming 0 => gravity existed before

    if gravity existed before, and therez a stationary object sitting there, it cannot sit there, it has to fall
