Answer 1

given below is your answer

Answer 2

Answer :

☞ Option B

Explanation :

y = x tan θ - gx^2 / 2u^2 cos^2 θ

we get, tan θ = 1 / √3

=> θ = 30°

and 2u^2 cos^2 θ = 20

=> u^2 = 20 / 2 cos^2 θ

=> 10 / cos^2 30°

=> 10 / ( √3 / 2 ) ^2

=> 40 / 3

Now, Rmax = u^2 / g

=> 40 / 3 × 10

=> 40 / 30

=> 4 / 3
