A collar $B$ of mass $2 kg$ is constrained to move along a horizontal smooth and fixed circular track of radius $5 m$ . The spring lying in the plane of the circular track and having spring constant $200 Nm^{- 1}$ is undeformed when the collar is at $A$ . If the collar starts from rest at $B$ , the normal reaction exerted by the track on the collar when it passes through $A$ is

Text solutionVerified

E_{A} = E_{B}

∴ \frac{1}{2} m v_{A}^{2} = \frac{1}{2} \times 200 \times (13 - 7)^{2} (m = 2 kg)

∴ v_{A} = 60 m / s

A, N = \frac{m v _{A}^{2}}{R} = \frac{( 2 ) ( 60 ) ^{2}}{S} = 1440 N
