Consider the following statements: A 4-wheel vehicle moving in a sharp circular path at high speed will: ​1. Overturn about its outer wheels ​2. Overturn about its inner wheels ​3. Skid outwards4. Skid inwards ​ Which of these statements are correct?

a1 and 3
b​2 and 4
c2 and 3
d1 and 4
✓ Correct answer: a) 1 and 3
ExplanationStatement 1 is correct: When a vehicle takes a sharp turn at high speed, the centrifugal force may push the vehicle outwards.This can cause the vehicle to tilt outwards and potentially overturn about its outer wheels.Statement 2 is incorrect: This is less likely to happen.The centrifugal force pushes the vehicle outwards, not inwards.Statement 3 is correct: If the friction between the tires and the road is insufficient to provide the necessary centripetal force, the vehicle may skid outwards, away from the center of the turn.Statement 4 is incorrect: Skidding typically occurs outwards, not inwards, due to the centrifugal force.222
