Using Newton's second law we can know the direction of the force that creates the uniform circular motion, the correct answer is:
C) The force must go towards the center of the circle
Newton's second law establishes a linear relationship between force and mass of the body and its relationship is
F = m a
The bold letters indicate vectors, where F is the force, m the mass that is a scalar and the acceleration of the body
By analyzing this expression we see that the direction of the net force and the acceleration are the same,
The uniform circular motion is characterized by having a speed, speed modulus, constant therefore in the movement the acceleration vector must be perpendicular to the speed so that the change is of direction only.
The acceleration must go towards the center of the circle and by Newton's second law the net force must also go towards the center of the circle.
Let's analyze the different strengths of the graph
a and d) Tangential force to the circle
False. This force changes the modulus of the velocity so the movement stops being uniform circular
e) outward perpendicular force
False. This force changes the direction of the velocity and maintains its modulus, but the antiparallel to the acceleration which contradicts Newton's second law
b) Force at an angle.
False. This force can be decomposed into two vectors, one parallel and the other perpendicular to the circle, the parallel vector combines the speed modulus and the movement is elliptical.
c) Force towards the center of the circle.
True. This force changes the direction of the velocity and maintains its modulus, in addition, the acceleration is in the direction of the change in velocity, which is why the particle describes the circle.
Using Newton's second law we can know the direction of the force that creates the uniform circular motion having the correct answer is:
c) The force must go towards the center of the circle
