Two trains one of length 100 m and another of length 125 m , are moving in mutually opposite directions along parallel lines, meet each other, each with speed 10 
. If their acceleration are 0.3 
and 0.2 
respectively, then the time they take to pass each other will be
Text Solution
Verified by ExpertsThe correct answer is:
B
Relative velocity of one train w.r.t . other
=10+10=20 m / s .
Relative acceleration =0.3+0.2=0.5 m / s 2
If trains cross each other then from

⇒ ⇒ 
⇒ ⇒ 
\ \
