AP EAMCET · PHYSICS · Motion In Two Dimensions
Assertion (A) The range of a projectile is maximum when the angle of projection is \(45^{\circ}\).
Reason (R) The range of a projectile depends only on the angle of projection.
- 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 & Solution
Correct Answer
(C) (A) is true but (R) is false.
Step-by-step Solution
Detailed explanation
Assertion is true. (A) The range of projectile is maximum when the angle of projection is \(45^{\circ}\). \(R_{\max }=\frac{u^2 \sin (2 \times 45)}{g}=\frac{u^2}{g}\) But reason \((R)\) is false. \(\therefore\) Range of a projectile, \(R=\frac{u^2 \sin 2 \theta}{g}\) Hence, the…
