zero
B
&
C
They meet at phase difference of π .
Text Solution
Verified by ExpertsThe correct answer is:
CHECK THE SOLUTION.
9 Ι 5 Ι Ι
Sol. We know that Ι res = Ι 1 + Ι 2 + 2 
cos ( φ )
Ι res = Ι + 4 Ι + 2 
× 2 
cos (0) = 9 I.
Ι res = Ι + 4 Ι + 2 
× 2 
cos 
= 5 I.
Ι res = Ι + 4 Ι + 2 
× 2 
cos (180) = I .
