    A uniform metal chain of mass mm and length ' LL ' passes over a massless and frictionless pulley. It is released from rest with a part of its length ' ll ' is hanging on one side and rest of its length ' L−lL - l ' is hanging on the other side of the pulley. At a certain point of time, when l=Lxl =\frac{L}{x}, the acceleration of the chain is g2\frac{g}{2}. The value of xx is

    An object is projected in the air with initial velocity uu at an angle θ\theta. The projectile motion is such that the horizontal range RR, is maximum. Another object is projected in the air with a horizontal range half of the range of first object. The initial velocity remains same in both the case. The value of the angle of projection, at which the second object is projected, will be ____\_\_\_\_ degree.
