A car travelling on a smooth road passes through a curved portion of the road in the form of an arc of circle of radius `10m`. If the mass of car is `120kg`, find the reaction (in kN) on car at lowest point P where its speed is `20ms^-1`.

A

2kN

B

6kN

C

10kN

D

12kN

Text Solution

Verified by Experts

The correct Answer is:
B
`N=mg+mv^2//r=120[10+20^2//10]=6,000N=6kN`
