Which of the following factors improve the chances of toppling of a vehicle1) low centre of gravity2) high ground clearance3) radius of curvature of the road is low4) radius of curvature of the road is high5) coefficiency of friction between tyre and the road is high6) coefficiency of friction between tyre and the road is low7) high centre of gravity8) low ground clearance*1,4,5,81,3,6,82,3,6,72,1,4,6

The factors that improve the chances of a vehicle toppling are:

1. High centre of gravity: A vehicle with a high centre of gravity is more likely to topple because the weight is distributed higher off the ground, making the vehicle less stable.

2. Low ground clearance: A vehicle with low ground clearance is closer to the ground, which can make it more likely to topple if it hits a bump or a pothole.

3. Low radius of curvature of the road: A road with a low radius of curvature means the road is more curved, which can increase the chances of a vehicle toppling, especially if the vehicle is moving at a high speed.

4. Low coefficient of friction between the tyre and the road: A lower coefficient of friction means there is less grip between the tyre and the road, which can make the vehicle more likely to slide or topple.

So, the correct answer is 2,3,6,7.
