For angles of projection of a projectile...

For angles of projection of a projectile at angles `(45^(@)` – θ) and `(45^(@) + θ)`, the horizontal ranges described by the projectile are in the ratio of:

A

` 1 : 1 `

B

`2 : 3 `

C

` 1 : 2 `

D

`2 : 1 `

Text Solution

Verified by Experts

The correct Answer is:
A
For complementary angles, rnage will be same
OR
`(R^(1))/(R^2)=[[(u^(2)sin 2(45-0))/(g)]/[[u^(2) sin2(45+0))/(g)]]=(u^(2)sin(90-20))/(u^(2)sin(90+20))`
