A conical frustum of height h has been placed with its axis vertical A particle of mass m is projected horizontally with velocity vo along its upper brim The radii of its upper and lower cross sections are R and r R 2 respectively The particle slides along the inner surface in spiral path without friction and leaves the lower face at point B a Find the horizontal and vertical B component of velocity of the particle as it leaves the frustum at B b Find minimum value of h for which the particle will neve out of the frustum Vertical axis A R 10 h
