A) \[1:3:5\]
B) \[1:2:3\]
C) \[1:4:9\]
D) \[1:5:6\]
Correct Answer: A
Solution :
According to equation of motion, distance covered in nth sec. \[{{S}_{n}}=u=\frac{a}{2}(2n-1)\] \[{{S}_{n}}=\frac{a}{2}(2n-1)\] \[\therefore \] \[{{S}_{1}}:{{S}_{2}}:{{S}_{3}}\] \[=\{2(1)-1\}:\{2(2)-1\}:\{2(3)-1\}\] \[=1:3:5\]
