Solution

The correct option is A range of projectile
$T = \frac{2 u s i n θ}{g}; H = \frac{u^{2} s i n θ}{2 g}; R = \frac{u^{2} s i n 2 θ}{g}$
all the quantities will change for $θ = 30^{o} o r 60^{o}$ but R will remain the same as $s i n 2 θ$ is same for $30^{o} a n d 60^{o}$

Two projectiles of same mass and with same velocity are thrown at an angle 60 and 30 with the horizontal, then which quantity will remain same

The correct option is A range of projectileT=2usinθg;H=u2sinθ2g;R=u2sin2θgall the quantities will change for θ=30oor 60o but R will remain the same as sin2θ is same for 30oand 60o
