Answer

3.3 m, so the answer is b) 3.3 m

Explain

## Step1: This a question related to faradays induction process.<br /><br />## 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.<br />The formula is: <br /><br />### \( V = B * l * v \)<br /><br />Where,<br />\( V \) = Voltage (Volts)<br />\( B \) = Magnetic field strength (Tesla)<br />\( l \) = Length of conductor (meters)<br />\( v \) = speed (m/s)<br /><br />## Step3: We need to solve the formula for length of the conductor \( l \) :<br /><br />### \( l = \frac{ V }{ B * v } \)<br /><br />## Step4: Substitute the given equation component; \( V = 12V, B = 0.9 T, v = 4 m/s \) into the formula to obtain the length :<br /><br />### \( l = \frac{12 V}{0.9 T * 4 m/s} = 3.3 m \)
