Hi, in the given problem there are two parallel conducting tracks which are connected with the help of a battery, a source of potential whose positive terminal is connected with the conductor which is due east.
00:27
This is east, this is west, so this is north and here it will be south.
00:32
There is a magnetic field in this region which is directed out of the plane of paper perpendicularly like this.
00:48
Now the gap between the parallel conducting rails here this gap actually there is a metallic rod also which is free to slide over these two rails without any friction.
01:04
So length of effective length of the rod, metallic rod, will be actually equal to the gap between the rails.
01:13
So effective length of the rod means l, that is equal to the gap between the parallel metallic rails.
01:41
And this is given as 0 .50 meter length of the rod and mass of this rod is m is equal to 0 .0.
02:02
This is 50 gram which can also be written as 0 .050 kilogram...
