Here, we will apply equilibrium of equation summation of ma is equal to zero.
00:24
Okay.
00:25
So, from here like c zero minus of rc xl is equal to zero.
00:31
So, from here the rc is equal to c zero divided by n.
00:36
After getting this, summation of mc is equal to zero, which is like the plus, this is for minus, okay, c zero minus of ra xl is equal to zero.
00:52
So, from here, this ra is equal to c zero divided by n.
00:56
At point a, what's happening here? at point a, va is equal to ra is equal to minus c zero divided by n.
01:13
After that, okay, we got the value of the v and ma is equal to zero.
01:18
So, this is the thing we are getting at point a.
01:23
Now, if we talk about at point b, what's happening here? let's see.
01:30
That is vb is equal to minus c zero upon l...
