    Since speed of the particle decreases with height, hence tension is maximum at the bottom, where cos θ = 1 (as θ = 0). => T max = mv 2 /R + mg; T min = mv '2 /R mg (at the top) Here, v ' = speed of the particle at the top. Critical Velocity. It is the minimum velocity given to the particle at the lowest point to complete the circle.
