PHXI04:MOTION IN A PLANE

362013 Assertion :
The maximum height of projectile is always \(25 \%\) of the maximum range
Reason :
For maximum range, projectile should be projected at \(90^{\circ}\)

1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but reason is correct.
PHXI04:MOTION IN A PLANE

362014 Two projectiles \(A\) and \(B\) are thrown with initial velocities of \(40\;m{\rm{/}}s\) and \(60\;m{\rm{/}}s\) at angles \(30^{\circ}\) and \(60^{\circ}\) with the horizontal respectively. The ratio of their ranges respectively is \(\left( {g = 10\;m{\rm{/}}{s^2}} \right)\)

2 \(1: 1\)
3 \(\sqrt{3}: 2\)
4 \(2: \sqrt{3}\)
PHXI04:MOTION IN A PLANE

362015 Keeping the velocity of projection constant, the angle of projection is increased from \(0^\circ \) to \(90^\circ \), then the horizontal range of the projectile

1 Goes on increasing upto \(90^\circ \)
2 Decreases upto \(90^\circ \)
3 Increases upto \(45^\circ \) and decreases afterwards
4 Decreases upto \(45^\circ \) and increases afterwards

362016 Galileo writes that for angles of projection of a projectile at angles \((45 + \theta )\) and \((45 - \theta )\), the horizontal ranges described by the projectile are in the ratio of \(({\mathop{\rm if}\nolimits} \;\theta \le 45)\)
