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

Option: 1


Option: 2


Option: 3


Option: 4


Answers (1)

best_answer

The normal reaction on the block by the wall provides necessary centripetal force

\mathrm{N=\frac{mv^{2}}{R}}

\mathrm{R\rightarrow }Radius of the circle

\mathrm{N\: \: \alpha\: \: v^{2}}

Hence 1 is correct option
