A car is moving with speed of ` 10 m//s ` in a concave road of radius 100 m .If the mass of the car is 700 kg, then the reaction on the car tyres when it is at the lowest position will be

4560 N

5560 N

6560 N

7560 N

Text Solution

Verified by Experts

The correct Answer is:

`N_(L)=(mv^(2))/(r)+mg`
`=(700xx100)/(100)+700xx9.8=700+6860`
`=7560 N`.
