1.	Fig. show a conical pendulum. If the length of the pendulum is l, mass of die bob is m and thetais the angle made by the string with the vertical show that the angular momentum of the pendulum about the point of support is: L = sqrt((m^(2)gl^(3) sin^(4)theta)/(cos theta))
Answer» Solution :When the mass m is at the top of the wedge the component of the weight parallel to the sloping side provide the necessary centripetal force. `MG sin THETA = (mv^(2))/L , v= sqrt(LG sin theta)`
