In this question, we have this setup.
00:03
So, you know, there's a circuit, so there are two metal rails, okay? and then there's a resistor that's connected across, and then there's a rod that's being slide across, and then the whole region is in a magnetic field that's pointing into the page.
00:31
Okay, so as this meta -brate slides to the right, with a speed v, okay, motional emf is generated.
00:43
And so in this question, we are asked to find the speed if the motioner emf is one volt, okay? emf is one volt, and then the magnetic field is 1 .5 tesla.
01:09
Okay, then the length of the rod is 30 cm, which is 0 .3 meters.
01:16
We want to find v...
