A car is travelling along a flyover bridge which is a part of vertical circle of radius `10m`. At the highest point of it the normal reaction on the car is half of it’s weight, the speed of car is

A

`7m//s`

B

`10m//s`

C

`14m//s`

D

`20m//s`

Text Solution

Verified by Experts

The correct Answer is:
A
Normal reaction, `N = mg - (m v^(2))/(r )`
Given that `N = (mg)/(2)`
