A block of mass m is released from a height h1 along a
smooth track as shown in the figure.
Determine the force exerted on the block by the track at point 2, where radius of curvature is r1 .
- \(m g+\frac{m\left(2 g h_{1}\right)}{r_{1}}\)
- \(2 m g+\frac{m\left(2 g h_{1}\right)}{r_{1}}\)
- \(\frac{m g}{2}+\frac{m\left(2 g h_{1}\right)}{r_{1}}\)
- \(m g+\frac{m\left(g h_{1}\right)}{r_{1}}\)
Answer
(A) m g+ m (2 g h_ 1 ) r_ 1
