Acertain object is in equilibrium. which one of the following statements is not true?
a. the object has a constant velocity.
b. the object must be at rest.
c. the object has no acceleration.
d. no net force acts on the object.

Answer And Explanation: The equilibrium of an object means that the net force acting on it in the x and y direction are zero indivisually.

2

If the net force is zero, means that the acceleration of the object must be zero.

3

Newton's First Law states that an object will remain at rest or in uniform motion in a straight line unless acted upon by an external force.

4

Since the force acting on it zero, means that the object may be at rest or it may be moving with constant velociy.

RESULT

(a)

PLEASE MARK ME BRAINLIEST :)

d. No net force acts on the object.

Explanation:

equilibrium - a state in which opposing forces or influences are balanced.
