NEET Physics (general) Assertion Reason Question
Type: Assertion Reason-assertion-Easy-Class 11
Assertion (A): The maximum horizontal range of a projectile is achieved at a launch angle of 45°. | Reason (R): The horizontal range is determined by the factor sin 2θ₀, which is maximum at θ₀ = 45°.
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.
Correct Answer
Option A
Detailed Explanation
The horizontal range R is given by the formula R = (v₀²/g) sin 2θ₀. The function sin 2θ₀ reaches its maximum value when 2θ₀ = 90°, which corresponds to θ₀ = 45°.
