Compute the radius of curvature of this film given that the radii of the bubbles in this arrangement are r_(1) and r_(2) respectively. If r_(1) gt r_(2) state clearly which way the intermediate film will bulge. For the case when r_(1)=r_(2)=2cm calculate he radius of the bubble formed by bursting the intermediate film. The volume of a spherical dome of radius R and height h is pib^(2)(3R-b)//3.

A circular ring of mass M and radius 'a' is placed in a gravity free space. A small particle of mass m placed on the axis of the ring at a distance sqrt(3)a from the center of the ring is released from rest. The velocity with which the particle passes through the center of the ring is
