|Assertion : Artificial satellites are always launched from the earth in the eastward direction.|
|Reason (R): The earth rotates from west to east and so the satellite attains the escape velocity.|
A) Both A and R are true and R is the correct explanation of A
B) Both A and R are true but R is not a correct explanation of A
C) A is true but R is false
D) A is false but R is true
Correct Answer: C
Solution :[c] Artificial satellites are always launched from the earth in the eastward direction as the earth rotates from west to east. It makes the satellite geosynchronous. But the escape velocity of 1.2 m/s is given by the booster of the rocket and has nothing to do with the direction of launching the satellite.
