Question

A projectile fired with initial velocity v at some angle θ has a range R. If the initial velocity be doubled at the same angle of projection, then the range will be (A) R / 2 (B) R (C) 2R (D) 4R

R=(u2 sin 2 θ/g) If u is doubled, R the range will be quadrupled

Q. A projectile fired with initial velocity $v$ at some angle $θ$ has a range $R$ . If the initial velocity be doubled at the same angle of projection, then the range will be

$R /2$

$R$

$2 R$

$4 R$

$R = \frac{u ^{2} s i n 2 θ}{g}$
If $u$ is doubled, $R$ the range will be quadrupled

Q. A projectile fired with initial velocity v at some angle θ has a range R. If the initial velocity be doubled at the same angle of projection, then the range will be

R/2

2R

4R

R=gu2sin2θ​ If u is doubled, R the range will be quadrupled
