Hello everyone.
00:01
So in a given situation the potential energy for a conservative force, u is equivalent to a ax square minus of a bx, where a and b is considered as a constant.
00:18
Okay, find out the expression of a force.
00:21
So guys, we know that if this is the expression of a u represent the potential energy.
00:27
So f is equivalent to a minus.
00:30
Minus of a d u by d x okay.
00:34
U is the function of a x in the, so d by d x, the function is a ax square minus of a bx, okay? minus is a taking out, a is a constant, so x square becomes a 2x.
00:52
Okay, students, now this is a negative sign, b is a constant and x becomes a 1, okay? now.
00:59
So we can write here that is a force is equivalent to minus of a 2 a x and minus minus becomes a plus so that is a b.
01:07
So this is the expression of a force.
01:10
Now we will calculate a b point that is the equilibrium position...
