Question

If for a given angle of projection, the horizontal range is doubled, the time of flight becomes: (A)  (1/√2) times (B)  √2 times (C) 2 times (D) 4 times

Since, time of flight T propto √R (where R= horizontal range of flight) when R is doubled the time of flight will become √2 times.

Q. If for a given angle of projection, the horizontal range is doubled, the time of flight becomes:

$\frac{1}{2}$ times

$2$ times

2 times

4 times

Since, time of flight $T \propto R$ (where R= horizontal range of flight) when R is doubled the time of flight will become $2$ times.

Q. If for a given angle of projection, the horizontal range is doubled, the time of flight becomes:

2​1​ times

2​ times

2 times

4 times

Since, time of flight T∝R​ (where R= horizontal range of flight) when R is doubled the time of flight will become 2​ times.

$\frac{1}{2}$ times

$2$ times

Since, time of flight $T \propto R$ (where R= horizontal range of flight) when R is doubled the time of flight will become $2$ times.
