Four particles are fired with the same velocities at angles 250^@, 40^@, 55^@ and 70^@with the horizontal. The range of projectile will be largest for the one projected at angle

Four particles are fired with the same velocities at angles 250^@, 40^

1.	Four particles are fired with the same velocities at angles 250^@, 40^@, 55^@ and 70^@with the horizontal. The range of projectile will be largest for the one projected at angle
Answer» `25^@` `40^@` `55^@` `70^@` Solution :`R=(u^2sin2 THETA)/(G)` In this case, `sin2theta` is the largest for ` theta = 40^@` , as compared to that for `theta = 25^@ , 55^@ , 70^@` .
