Question

    What will happen if an object is launched into space at a

    speed of 8 km/sec?
    A The object will go into space Correct Answer Incorrect Answer
    B It will return to Earth Correct Answer Incorrect Answer
    C It will enter Earth's orbit Correct Answer Incorrect Answer
    D It will burst Correct Answer Incorrect Answer

    Solution

    Earth's escape velocity is 11.2 km/sec, which is the minimum speed required for an object to completely escape Earth's gravitational pull. Since 8 km/sec is below this threshold, the object would not have sufficient velocity to escape Earth's gravity and would eventually return to Earth.
