Question

An object is subjected to a non-zero net force, $F$. Which of the following statements about its motion could not be true?

• A. The object will remain at rest
• B. The object has a constant velocity
• C. The object is travelling in a straight-line path with a constant speed
• D. The object is travelling in a circular path with a constant speed
• E. The acceleration of the object is perpendicular to the net force

Answer 1

The correct option is A The object will remain at rest

Net force on an object is directly proportional to the acceleration of the particle which is the rate of change of velocity.

When a body moves in a uniform circular motion, its velocity keep on changing though its speed is constant.
