Question

At turns, slopes are made on the road in order to

• A. Help the driver to drive slowly
• B. Reduce friction
• C. Help the vehicle to get the centripetal force
• D. Help the driver to retain balance while driving

Answer 1

Answer: (C)

Help the vehicle to get the centripetal force

On the turns, slopes are made on the roads, because on turns, a vehicle undergoes a circular motion, for this it requires a centripetal force. If vehicle doesn't get centripetal force, it will slip out from the road. Due to slope, the horizontal component of reaction force on the vehicle provides the necessary centripetal force and vehicle can take turn easily.
