A pendulum is constructed by attaching a very light-weight string to a cylinder of radius R and wrapping the string around the cylinder so that a mass m at the end of the string forms a pendulum in a plane perpendicular to the axis of the cylinder. Assume that the unwrapped part of the string remains straight. What is the equation of motion? What quantities are conserved? What is the frequency of small oscillations? Around which angle are the oscillations equal in angular amplitude?

the order for strong to weak forces such as

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

the fundamental forces are those forces that act between to objects or element to make interactions. there are four types of fundamental forces such as strong and weak nuclear forces (due to protons and electrons), electromagnetic force (due to the motion of electrons) and gravitational force (due to orbital movement of the planet). if these forces are arranged on the basis of their maximum strength then the order is

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force
