Question

Acceleration of a body can be zero when

• A. No force is acting on it
• B. One force of infinite magnitude is acting on it
• C. Multiple forces are acting on it
• D. Can never be zero

Answer 1

Answer: (A), (C)

The correct options are
A No force is acting on it
C Multiple forces are acting on it

According to newton's first law of motion, the acceleration of the body could be zero if there is no force acting on it. Acceleration in an object could be zero even when several forces acting on it.This happens when all the forces cancel out each other i.e the net force acting on the object is zero.For a uniformly moving object,the net force acting on the object is zero.Hence,the acceleration of the object is zero.
