The range of a projectile fired at an angle of `15^@` is 50 m. If it is fired with the same speed at an angle of `45^@` its range will be

A

`60 m`

B

`71 m`

C

`100 m`

D

`141 m`

Text Solution

Verified by Experts

The correct Answer is:
C
`R=50m=(u^(2)sin(2xx15^(@)))/g`
`u=31.304m//s`
`theta=45^(@),R=(u^(2)sin(2xx15^(@)))/g=100m`
