141966 A block at rest slides down a smooth inclined plane which makes an angle \(60^{\circ}\) with the vertical and it reaches the ground in \(t_{1}\) seconds. Another block is dropped vertically from the same point and reaches the ground in \(t_{2}\) seconds. Then the ratio of \(t_{1}: t_{2}\) is

141967 A frictionless wire \(A B\) is fixed on a sphere of radius \(R\). A very small spherical ball slips on this wire. The time taken by this ball to slip from \(A\) to \(B\) is

141968 An object is placed on a smooth inclined plane of 1 in \(l\). The horizontal acceleration to be imparted to inclined plane so that, the object is stationary relative to the inclined is given by

141969 A mass \(m\) is placed on a wedge (triangular block) of mass \(M\). The wedge moves on a smooth horizontal surface what should be the force \(F\) applied on the wedge to the right. so that \(m\) remains stationary with respect to wedge. (Ignore any friction)
