an artificial satellite is orbiting the earth. A bomb is released from the satellite. The bomb will
(a)explode due to the heat generated by the friction of air
(b)fall freely on the earth
(c)escape into outer space
(d)orbit the earth along with the satellite

What a funny question. How can there be air friction where there is no air?
What happens to astronauts who leave space station for extravehicular activity? Do they have to remain tied to the ship to avoid falling to earth or "escaping to outer space"?
To change an object's orbit, an extra force has to be applied to it (besides Earth's gravity pull, which keeps it in orbit)
When the bomb is "released", it is presumably not been given a large extra force. It is just pushed out an open door. It will slowly drift away in the drection it was pushed, but after one orbit it will return to about the same place where it was released.
The correct answer is (b) fall freely on the earth.
When a bomb is released from an artificial satellite, it is no longer in orbit and is no longer subject to the satellite's gravitational pull. Without the satellite's velocity to maintain its orbit, the bomb will be subject to Earth's gravity and will fall towards the Earth. The bomb will descend in a free-falling motion due to the gravitational force until it reaches the Earth's surface.
The correct answer is (b) the bomb will fall freely on the Earth.
When an artificial satellite is in orbit around the Earth, it is essentially in a state of free fall. This means that it is continuously falling towards the Earth, but at the same time, it is also moving forward at a sufficiently high speed so that it continues to miss the Earth as it falls.
If a bomb is released from the satellite, it will also be in a state of free fall. However, since the bomb is no longer attached to the satellite, it will not have the same initial speed as the satellite. As a result, the bomb will not have enough velocity to maintain a stable orbit around the Earth. Instead, it will simply fall towards the Earth under the influence of gravity.
It is important to note that option (a) is incorrect because the friction of air would not generate enough heat to cause the bomb to explode. Option (c) is incorrect because the bomb does not have enough velocity to escape into outer space. Option (d) is incorrect because once the bomb is released, it will no longer be in orbit along with the satellite.
