A) \[a/\sqrt{{{v}^{2}}+v_{1}^{2}}\]
B) \[\sqrt{{{a}^{2}}/({{v}^{2}}-v_{1}^{2})}\]
C) \[a/(v-{{v}_{1}})\]
D) \[a/(v+{{v}_{1}})\]
Correct Answer: B
Solution :
Let two boys meet at point C after time 't' from the starting. Then \[AC=vt,\,BC={{v}_{1}}t\] By solving we get \[\sqrt{\frac{{{a}^{2}}}{{{v}^{2}}-v_{1}^{2}}}\]You need to login to perform this action.
