An areoplane files from P and Q with speed v and then from Q and P with the same speed. If wind blows normal to straight line PQ with the speed V, the total time for to and for motion is
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
A
The aeroplane has to follow a path such that resultant of v and V should be in line with PQ
Thus R = 
time taken to cover distance PQ = L/ 
Since velocity is the same during return also/time taken to cover distance QP = L/ 
.
Thus, total time = L/
