Question

When a car takes a sudden turn, it is likely to fall:

• A. away from the centre of curvature.
• B. towards the centre of curvature.
• C. in the forward direction.
• D. in the backward direction

Answer 1

The correct option is A away from the centre of curvature.

When a car takes a sudden turn, the radius of curvature (here, radius of turning) decreases while keeping the mass and speed nearly constant. Hence the centrifugal force i.e. $\frac{m{v}^2}{r}$ suddenly increases making the car to be pushed away from the center of curvature.
