Answer:
induced emf = 28.65 mV
Explanation:
given data
diameter = 7.3 cm
magnetic field = 0.61
time period = 0.13 s
to find out
magnitude of the induced emf
solution
we know radius is diameter / 2
radius = 7.3 / 2
radius = 3.65 m
so induced emf is dπ/dt = Adb/dt
induced emf = A × ΔB / Δt
induced emf = πr² × ΔB / Δt
induced emf = π (0..65)² × ( 0.61 - (-0.28)) / 0.13
induced emf = 0.0286538 V
so induced emf = 28.65 mV
here our distance is given with respect to ticket booth
initial distance is given 50 m from the booth
So our initial position is
now after this finally we reach at final position
now change in position is given as
<em>so change in position is 45 m in magnitude and since we are coming closer to the booth so its coming negative in sign</em>
