3.3 m, so the answer is b) 3.3 m
Explanation
## Step1: This a question related to faradays induction process.## Step2: Firstly, the formula which will be used to solve this question is Faraday's Law of electromagnetic induction, indicates that the absolute value or magnitude of the circulation of the electric field E round stage at circular a boundary B that is shared by the open surface S is equal to the rate of change of the magnetic flux ΦB through thereby.The formula is: ###
Where,
= Voltage (Volts)
= Magnetic field strength (Tesla)
= Length of conductor (meters)
= speed (m/s)## Step3: We need to solve the formula for length of the conductor
:###
## Step4: Substitute the given equation component;
into the formula to obtain the length :###
