6 . Direction (Q. 6 to 10): Read the following passage and answer the questions given below it. A few words have been given in bold so as to help you locate them for the answers to some of the questions.
Isaac Newton, the English scientist proposed some new basics of physics to the world. He questioned “If the apple could fall, why the moon held on?” He discovered that against the gravitational pull of the earth, the force of a moving moon balanced it and thus preventing it from falling off. He enunciated his law that “All heavenly bodies attract one another and the universal gravitation pervades the whole of nature and governs the motion of all the bodies. Newton’s famous third law of motion, which states that “to every action, there is an equal and opposite reaction”, has become the basis of rocket and missile propulsion. Thus was published his Principia in 1687, where he gave three prerequisites for a satellite—it should be fast enough, it should be afar the atmosphere, it must be projected horizontally. After Newton, the Russian scientist Tsiolovsky, often regarded as the founder of astronautics, proved that man could go into space only by a rocket. To provide the proper thrust to the rocket, various propellant combinations were suggested, owing to the dimensions and weight of the rocket. A single stage rocket would need fuel roughly four times its own weight but this need would be considerably less if the rocket were in stages. He proposed that if the velocity of combusted gases rushing backwards from the rocket was high, this would result in an increase in its forward thrust. Sputnik I was the first jump by mankind into space. It was a three-stage rocket launched by Russia. Space technology has been completely revolutionized by the application of transistors and computers.
Nature facilitates the satellite launching by a decrease in the gravitational pull of earth, as we move away from the earth’s surface. To avoid resistance of the atmosphere, a satellite is first taken to a height of 150 km and launched horizontally. For this, a minimum velocity of nearly 8 km per second is required, which means about 28,800 km/hr.
Q. What does the author mean to say, when he says “nature facilitates the satellite launching by a decrease in the gravitational pull of the earth”?
A.   While launching a satellite, we take facilities from the nature.
B.   Since gravitational pull decreases as we come close to earth, satellites can be launched easily from earth.
C.   With the increase in distance from earth, gravitational pull decreases and this makes satellite launching more convenient.
D.   Nature is always helpful due to its gravity, to launch satellites from the earth.

A.   Transistors and computers have helped in space technology also.
B.   The more the stages, the better the rocket.
C.   Rockets use fuels according to their weight and size.
D.   The apple and the moon followed different physical laws.

8 . Which of these is true?
A.   Newton gave only the third law of physics
B.   All bodies react with each other
C.   Man can go into space by increasing his rocket's speed to 8 km/sec
D.   Principia was written by Newton.

9 . What does the author convey to us when he says that “force of moving moon balanced it”?
A.   Moon applies force on earth to move away from it.
B.   Moon tries to move in an orbit
C.   Moon and earth exert forces on each other.
D.   None of these
View Answer
10 . What makes multi-stages in a rocket important?
A.   Multistages uses multiple engines, so more thrust can be provided to the rocket.
B.   Multistages help in various stages of launch
C.   Multistage rockets consume less fuel for launching a satellite.
D.   Multistage rockets reduce the weight of the satellite.
