MCQ
The maximum range of a gun on horizontal terrain is $16 \,km$. If $g = \;10m/{s^2}$. What must be the muzzle velocity of the shell ......... $m/s$
- A$800$
- ✓$400$
- C$160$
- D$200\sqrt 2$
✓
Answer
Correct option: B.
$400$
b
(b) ${R_{\max }} = \frac{{{u^2}}}{g} = 16 \times {10^3}$
(b) ${R_{\max }} = \frac{{{u^2}}}{g} = 16 \times {10^3}$
$⇒$ $u = 400\,m/s$
