A potential energy function is given by u(x) = (3.00 n/m)x - (1.00 n/m3)x3. at what position or positions is the force equal to zero?'

Respuesta :

The position at which force is equal to 0 is +1 and -1.

The potential energy of the function is U.

U = 3x + 1 x²

Force is F.

F = 0

[tex]F = \frac{ - dU}{dx}[/tex]

[tex]F= \frac{ - d(3x + 1x ^{2} }{dx} [/tex]

= ( -3 - 3 x²)

= -3 ( 1+ x²)

As the force is zero.

The position at which force is equal to 0 is,

0 = -3 ( 1 + x ²)

[tex]x = \sqrt{ 1} [/tex]

x = 1

Therefore, the position at which force is equal to 0 is +1 and -1.
