A) 3 km
B) 6 km
C) 3 m/s
D) 4 m/s
Correct Answer: B
Solution :
Let \[x\] be the distance between \[A\] and \[B\], then \[x=u\sqrt{\frac{2h}{g}}\] Here, \[h=1.96\,\,km=1960\,\,m\] \[\therefore \] \[x=300\sqrt{\frac{2\times 1960}{9.8}}\] \[=6000\,\,m=6\,\,km\]You need to login to perform this action.
