प्रश्न
Give a reason for the following.
Vehicles skid on muddy and wet roads. Suggest what type of tires can prevent skidding of vehicles?
उत्तर
Vehicles slip/skid on muddy and wet roads as the roads become smooth and offer less friction to the tyres. Tyres are therefore grooved or treaded to make their surface rough so that the friction between the tyres and the road increases and vehicles may stop easily when desired.
