Study Case : Q. 11 to 15 |
SLV-3 was successfully launched on July 18, 1980 from Sriharikota Range (SHAR), when Rohini Satellite, RS-1, was placed in orbit, thereby making India the sixth member of an exclusive club of space-faring nations. |
SLV-3 employed an open loop guidance (with stored pitch programme) to steer the vehicle in flight along a predetermined trajectory. The successful culmination of the SLV-3 project showed the way to advanced launch vehicle projects such as the Augmented Satellite Launch Vehicle (ASLV), Polar Satellite Launch Vehicle (PSLV) and |
Geosynchronous Satellite Launch Vehicle (GSLV) Students of Class-Xth made a mathematical model of a rocket as shown in the figure below: |
Based on the above information give the answer of the following questions: |
A) \[(4,9)\]
B) \[(5,9)\]
C) \[\left( \frac{9}{2},9 \right)\]
D) \[(4,8)\]
Correct Answer: C
Solution :
As the distance of point A is \[\frac{9}{2}\] units from the Y-axis and 9 units from the X-axis, its coordinates are |
\[x=\frac{9}{2},\] \[y=9\] or \[\left( \frac{9}{2},9 \right)\] |
So, option [c] is correct. |
