PhysicsEasysingle choice

A small block is shot into each of the four tracks as shown below. Each of the tracks risks to the same height. The speed with which the block enters the track is the same in all cases. At the highest point of the track, the normal reaction is maximum in

Options:

Answer:

Solution:

At the highest point let $v'$ is the speed

$\frac{m v^{' 2}}{R} = m g + N \Rightarrow N = \frac{{mv}^{' 2}}{R} - m g \Rightarrow R is min for first case so N_{max}$
