When a body moves on a banked road ,why is the direction of frictional force acting is towards the centre of path followed rather then just opposing the translatory motion of body at a particular moment.?
When a body moves on banked roads, then it is in a kind of circular motion, when in this motion there acts a centrifugal force outwards, i.e away from the centre of the circle, and hence body has the tendency to move out, which is in return opposed by friction that acts inwards.
hope this helps

since the car moves in circular motion so there should be some force towards the center so that required centrifugal force is applied. so when a car is taking a turn there is no other force other than frictional force so that requirement of centrifugal force is completed therefore frictional force is applied towards the center.
or in the other words if suppose frictional force is applied away from the center so none of the car would be able to take a turn and would flip .
Three identical balls are placed on a frictionless
horizontal surface touching each other. They stick to
each other because of adhesive. Another ball of same
radius and mass m is placed over the void created by
the three balls. Find the forces applied by the balls
kept on the floor to each other if the system remains
in equilibrium.

A car loaded with water having total mass 1000 kg moves on a straight horizontal Road starting from rest under the action of a force of 100 Newton. The water spills throw a small hole in the bottom at a rate of 0.1 KG per second the velocity of cart after 300 seconds is nearly.
