N =( mv 2/ r ) Curve is parabola Y = kx 2

Q. 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) ?

$N = \frac{m v ^{2}}{r}$
Curve is parabola
$Y = k x^{2}$
