IN UNIFORM CIRCULAR MOTION ACCELERATION(a)has two formulaes a=RW^2 i.e (W=OMEGA) and a=v^2/r so is acceleration is directly or inversely proportional to r(radius)
u shuld ask dese kind of question maneesh gupta durin lecss....were u sleepin at dat time..
If during the motion, the angular velocity of the particle is constant, then the acceleration of the particle is directly propotional to r.
On the other hand if its linear velocity is constant throughout, then it is inversely proportional to r .
At a constant speed, the centripetal acceleration of an object in uniform circular motion is inversely proportional to the orbital radius, yet, at a constant period of revolution, the centripetal acceleration is directly proportional to the orbital radius.
therefore the question is incomplete.
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.
