Let an conducting Thin Rigid Rod of Length 'L' and mass 'm' is released under gravity from rest at time t=0 at an angular position \({ \theta }_{ 0 }\quad =\quad { 60 }^{ 0 }\) from horizontal.
There is gravity in -Y direction and uniform Magnetic Field of strength \({ B }_{ 0 }\quad \)
The Rod is sliding on the perfectly smooth Surface.
So Find the Magnitude of Motional EMF produced in Rod between The End Point A and Point P at the instant when Rod is making an angle \(\theta \quad =\quad { 30 }^{ 0 }\) from Horizontal.
Let your answer is \(\alpha \) Then Evaluate \(\left\lfloor 100\alpha \right\rfloor \).
