14. | Three particles A,B and C are projected from the same point with the same initial speed making angles 30°,45° and 60° respectively with the horizontal. Which of the following statements is correct? | |
A. | A, B and C have unequal ranges | |
B. | Ranges of A and C are equal and less than that of B | |
C. | Ranges of A and C are equal and greater than that of B | |
D. | A, B and C have equal ranges | |
Answer: Option B | |
Explanation: | |
RA = (u2 sin60°)/g = √3/2 u2 /g RB = (u2 sin90°)/g = u2 /g Rc = (u2 sin120°)/g = √3/2 u2 /g Ranges A and C are equal but less than that of B. |
