To find the frequency of rotation in rpm, we can use the formula:
f = (V)/(2πR)
where f is the frequency in Hz, V is the induced voltage in volts, and R is the radius in meters.
Given that the induced voltage V = 1.0 V and the radius R = 0.2 m, we can substitute these values into the formula:
f = (1.0)/(2π(0.2))
Simplifying this expression:
f = 1.0/(0.4π)
To convert this frequency from Hz to rpm, we can use the conversion factor:
1 rpm = 1/60 Hz
Therefore, the frequency in rpm is:
f(rpm) = (1.0/(0.4π))*(1/60)
Evaluating this expression:
f(rpm) ≈ 0.530 rpm
So, the frequency of rotation is approximately 0.530 rpm.
