Here are the answers to the questions on the image.

Question 7:
When a road is banked, the centripetal force on a car going round a bend is provided by both the horizontal component of the normal reaction force and the frictional force between the tires and the road. The normal reaction component is always present on a banked curve, and friction provides additional force if the car's speed deviates from the ideal banking speed.

The correct option is [B] normal reaction and frictional forces.

Question 8:
