F=-4bx⇒ K=4b T=2π √(m/4 b)=π √(m/b)

Q. A particle of mass $m$ in a unidirectional potential field have potential energy $U (x) = a + 2 b x^{2}$ where $a$ and $b$ are positive constants. Find time period of oscillation :-

$2 π \frac{2 b}{m}$

$2 π \frac{m}{2 b}$

$π \frac{m}{b}$

$π \frac{b}{m}$

$F = - 4 b x \Rightarrow K = 4 b$
$T = 2 π \frac{m}{4 b} = π \frac{m}{b}$
