A smooth circular groove has a smooth vertical wall as shown in figure. A block of mass m moves against the wall with a speed v. Which of the following curve represents the correct relation between the normal reaction on the block by the wall N and speed of the block v?

Solution

The required centripetal force will be provided by the normal reaction

N=mv2r

This equation is similar to y=kx2 which is a parabola.
