Students, let's understand this question.
00:02
So, horizontal component, that is t is equal to mg cos theta, and vertical component, this is f is equal to minus mg sine theta.
00:36
So negative sign is due to the restoring force.
00:42
Negative sign is due to the restoring force and according to newton's second law according to newton's second law force is equal to mass into acceleration so minus m g sine theta is equal to m a and here, m and m, that m, that is, will get cancelled.
01:30
So, a is equal to minus g theta as sine theta is concurrent to theta and theta is equal to x by r.
01:54
So, a is equal to minus g x by, sorry, x by l...
