Question

The diagram below represents a 2.0-kilogram toy car moving at a constant speed of 3.0 meters per second counterclockwise in a circular path with a radius of 2.0 meters. Toy car r = 2.0 m At the instant shown in the diagram, the centripetal force acting on the car is (1) 4.5 N north (3) 9,0 N north (2) 4.5 N west (4) 9.0 N west

    Answer:

    Centripetal force on the car is 9 N and towards the center of the circle

    Explanation:

    As we know that centripetal force is the essential force due to which an object will revolve in the circle

    So here centripetal force on the car is given as

    F_c = \frac{mv^2}{R}

    here we know that

    m = 2kg

    v = 3m/s

    R = 2 m

    so we have

    F_c = \frac{2 \times 3^2}{2}

    F_c = 9 N Towards the center of the circle
