Two particles A and B are performing SHM along x and y-axis respective

1.	Two particles A and B are performing SHM along x and y-axis respectively with equal amplitude and frequency of `2 cm` and `1 Hz` respectively. Equilibrium positions of the particles A and B are at the coordinates `[3 cm, 0]` and `(0, 4 cm)` respectively. At `t = 0 ,B` is at its equilibrium position and moving towards the origin, while A is nearest to the origin and moving away from the origin- Equation of motion of particle B can be written as-A. `y = (2 cm) cos 2 pit`B. `y = (4 cm) - (2 cm) cos 2pit`C. `y = (2 cm) sin 2 pit`D. `y = (4 cm) - (2 cm) sin 2pit`
Answer» Correct Answer - D As B is at its equilibrium position and moving towards negative exterme at `t = 0` so `y-4 = 0.2 sin (2pit + pi) rArr y= 4 -2 sin (2pit)`
