Figure shows a ball of mass m connected with two ideal springs of force constant k, kept in equilibrium on a smooth incline, suddenly right spring is cut. What is magnitude of instantaneous acceleration (in m/ $s^{2}$ ) of ball.

Answer:

Solution:

In equilibrium, the two spring forces balance the weight components, giving $k x = m g /2$

When the right spring is cut, only the left spring force $k x$ acts along its axis

Instantaneous acceleration: $a = \frac{k x}{m} = \frac{g}{2} = 5$ m/s $^{2}$
