What will be genotypic ratio in the `F_(2)` generation of a monohybrid cross ?

Options

A. (a) ` 30 ^@ `
B. (b)`60 ^@ `
C. (c)`75^@ `
D. (d)`45^@ `

Answer

C

Explanation

`u^(2)/g=40 rArr u=20m//s`
`t=(2u sin theta)/(g) and R=(I cos theta+20) ((2u sin theta)/(g))`
Using `(dR)/(d theta)=0," we get "cos theta=1/2 rArr theta =60^@)`
