Wave constant for EM wave k is
Wavelength of wave
B is correct makes more sense
Answer:
40.96%
Solution:
As per the question:
If the original radius be 'r' and the initial pressure difference be 'P':
After the drop, radius:
r' = 0.8r
After rise in pressure:
P' = 0.1 P
Now,
Rate of flow is given by:
R ∝
Thus
R' = 40.96%
