Hello students, in the question the lines of electric field are given, we need to find at point w and z where the electric field is stronger.
00:12
So that we can here state electric field will be stronger at point w and weaker at z because we know that electric field is given by the equation dv by dr.
00:39
Here dv means difference in potential.
00:43
We can see that difference in potential between the two lines is same here because 4 minus 3 is 1, 3 minus 2 again 1, 2 minus 1 again 1.
00:53
As difference is same, now field is depends upon distance between the lines.
01:02
If distance between the lines is minimum, field will be maximum as they are inversely proportional to each other.
01:11
Then if distance between the lines is maximum, field will be minimum.
01:15
So when we observe the diagram, here where w point is there, the field lines are closer to each other that means distance between them is minimum...
