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 (if `theta le 45`)

A

`1:1`

B

`2:3`

C

`1:2`

D

`2:1`

Text Solution

Verified by Experts

The correct Answer is:
A
`theta_(1)+theta_(2)=(45^(@)-theta)+(45^(@)+theta)=90^(@)`
`therefore R_(1)=R_(2)`
