A soldier fires a bullet in the air and at time ‘t’ the bullet travels along the path x = 2t, y = t – 2, z = 5 – t. Then the path of the bullet is a
Answer & explanation
Correct answer: option 2
x = 2t y = t - 2 z = 5 - t
so $\frac{x}{2}=t ~~~~\frac{y+2}{1}=t ~~~~\frac{z-5}{-1}=t$
so $\frac{x}{2}=\frac{y+z}{1}=\frac{z-5}{-1}$ → equation of straight line direction ratios (2, 1, -1)
Option: B
