Assertion A :Two identical balls A and B thrown with same velocity ‘u’ at two different angles with horizontal attained the same range R.

Question

Given below are two statements. One is labelled as Assertion A and the other is labelled as Reason R. 

Assertion A :Two identical balls A and B thrown with same velocity ‘u’ at two different angles with horizontal attained the same range R. If A and B reached the maximum height h₁ and h₂ respectively, then R = \(4\sqrt{h_1h_2}\)

Reason R: = Product of said heights.

Choose the CORRECT answer :

 (A) Both A and R are true and R is the correct explanation of A. 

(B) Both A and R are true but R is NOT the correct explanation of A

(C) A is true but R is false

(D) A is false but R is true

Answer 1

Correct option is (A) Both A and R are true and R is the correct explanation of A

For same range θ₁ + θ₂ = 90°
