A Particle is attached to the lower end of a uniform rod which is hinged at its other end as shown in the figure. The minimum speed given to the particle so that the rod performs circular motion in a verticle plane will be [length of the rod is l, consider masses of bopth rod and particle to be same]

Assertion One end of a massless rod of length l is hinged so that it is free to rotate in vertical plane about a horizontal axis. If a particle is attached to the other end of the rod, then the minimum speed at lower most position of the particle is sqrt(5gl) to complete the circular motion. Reason Work done by cnetripetal force on the particle is always zero.
