Question

In a horizontal spring-mass system, mass m is released after being displaced towards right by some distance at t = 0 on a frictionless surface. The phase angle of the motion in radian when it is first time passing through the equilibrium position is equal to

Easy

A

$\frac{π}{2}$
B

$π$
C

$\frac{3 π}{2}$
D

0

Solution

Equation of the SHM $x = A \cos (ω t)$ .
When $x = 0$ for the first time, phase $ω t = \frac{π}{2}$ .
