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 ?

Correct answer

0

Step-by-step solution

The required centripetal force will be provided by the normal reaction ⇒ N = m v 2 r This equation is similar to y = k x 2 which is a parabola.
