MCQ
Given that $u_x=$ horizontal component of initial velocity of a projectile, $u_y=$ vertical component of initial velocity, $R=$ horizontal range, $T=$ time of flight and $H=$ maximum height of projectile. Now match the following two columns.
| Column $I$ | Column $II$ |
| $(A)$ $u_x$ is doubled, $u_y$ is halved | $(p)$ $H$ will remain unchanged |
| $(B)$ $u_y$ is doubled $u_x$ is halved | $(q)$ $R$ will remain unchanged |
| $(C)$ $u_x$ and $u_y$ both are doubled | $(r)$ $R$ will become four times |
| $(D)$ Only $u_y$ is doubled | $(s)$ $H$ will become four times |
- ✓$( A \rightarrow q , B \rightarrow q , r , C \rightarrow r , s , D \rightarrow s )$
- B$( A \rightarrow s , B \rightarrow q , r , C \rightarrow r , s , D \rightarrow p )$
- C$( A \rightarrow p , B \rightarrow q , r , C \rightarrow r , s , D \rightarrow s )$
- D$( A \rightarrow q , B \rightarrow q , p , C \rightarrow r , s , D \rightarrow s )$
