Motion in A Plane question

2023 · 6 Apr · Shift 1 · Q46

JEE MainPhysicsMotion in A PlaneMCQ+4 / −1
Given below are two statements : one is labelled as Assertion A and the other is labelled as Reason R Assertion A : When a body is projected at an angle 45∘45^{\circ}45∘, it's range is maximum. Reason R : For maximum range, the value of sin⁡2θ\sin 2 \thetasin2θ should be equal to one. In the light of the above statements, choose the correct answer from the options given below:
  1. A
    Both A\mathbf{A}A and R\mathbf{R}R are correct and R\mathbf{R}R is the correct explanation of A\mathbf{A}A
  2. B
    A\mathbf{A}A is true but R\mathbf{R}R is false
  3. C
    A\mathbf{A}A is false but R\mathbf{R}R is true
  4. D
    Both A\mathbf{A}A and R\mathbf{R}R are correct but R\mathbf{R}R is NOT the correct explanation of A\mathbf{A}A
