The diagram shows a car of mass 1000 kg traveling at a constant speed of 30 m/s in the direction shown along a flat, level road which forms a circle of radius 50 m.
[See diagram below on the left]
Which row in the table gives both the magnitude of the resultant force on the car and the direction of the acceleration of the car at the instant shown?
[See table below on the right]
A. row 1
B. row 2
C. row 5
D. row 3
E. row 4

For this question, you should know the concept of Centripetal Force.
It is the force which causes a change in direction of velocity towards the center of the circular motion.
Its given by- Fc=mv^2/r
where, Fc= Centripetal force
Put the value in above formula and you will get required force.
As force is towards center, so it will be directed towards R.
