355715 In vertical circular motion, the ratio of kinetic energy of a particle at highest point to that at lowest point is

355716 A particle moves along a vertical circle of radius \(r\) with a velocity \(\sqrt{10 r g}\) at \(Y\). If \(T_{A}, T_{B}, T_{X}, T_{Y}\) represent tension at \(A\), \(B\), \(X\) and \(Y\), respectively, then

355717 A stone tied to a string of length \(L\) is whirled in a vertical circle with the other end of the string at the centre. At a certain instant of time, the stone at its lowest position has speed \(u\). The magnitude of the change in its velocity as it reaches a position where the string is horizontal is

355718 A 1- \(kg\) stone at the end of 1 \(m\) long string is whirled in a vertical circle at a constant speed of \(4\;m{s^{ - 1}}\). The tension in the string is \(6\;N\) when the stone is
