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.
Options
- ABoth (A) and (R) are true and (R) is the correct explanation of .
- BBoth (A) and (R) are true but is not the correct explanation of .
- C(A) is true but (R) is false.
- D(A) is false but is true.
Correct answer
C. (A) is true but (R) is false.
Step-by-step solution
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 is false.
(\therefore) Range of a projectile, (R=\frac{u^2 \sin 2 \theta}{g})
Hence, the range of projectile depends on the angle of projection (\theta) and initial velocity .
(\therefore) (A) (\rightarrow) True
(B) (\rightarrow) False
