MCQ

Two projectiles are thrown simultaneously in the same plane from the same point. If their velocities are $v_1$ and $v_2$ at angles $\theta _1$ and $\theta_2$ respectively from the horizontal, then answer the following question

If $v_1\,\,sin\,\,\theta _1 = v_2\,\,sin\,\,\theta _2$, then choose the incorrect statement

A
the time of flight of both the particles will be same
B
the maximum height attained by the particles will be same
C
the trajectory of one with respect to another will be a horizontal straight line
✓
none of these

✓

Answer

Correct option: D.

none of these

d
$y=\frac{V_{21(y)}}{v_{21(x)}} x \Rightarrow y=\frac{v \sin \theta_{2}-\sin \theta_{1}}{v\left(\cos \theta_{2}-\cos \theta_{1}\right)} x$

$y=\frac{\sin \theta_{2}-\sin \theta_{1}}{\cos \theta_{2}-\cos \theta_{1}} x$
