Answer:
The induced emf is
Explanation:
From the question we are told that
The radius of the circular loop is
The intensity of the wave is
The wavelength is
Generally the intensity is mathematically represented as
Here is the permeability of free space with value
B is the magnetic field which can be mathematically represented from the equation as
substituting values
The area is mathematically represented as
substituting values
The angular velocity is mathematically represented as
substituting values
Generally the induced emf is mathematically represented as
At maximum induced emf
So
substituting values
data which is expressed in form of following way
here in above expression
= true value
= uncertainty in the value
now the relative uncertainty is given as
now by above formula we can say
a) 2.70 ± 0.05cm
here
True value = 2.70
uncertainty = 0.05
Relative uncertainty = = 0.0185
b) 12.02 ± 0.08cm
here
True value = 12.02
uncertainty = 0.08
Relative uncertainty = = 0.00665
