Question

4. Select incorrect statement(s).
(1) Zero acceleration of a particle does not
necessarily mean that its velocity is zero
(2) Negative acceleration of a particle does not
necessarily mean that speed of particle is
decreasing
(3) Zero velocity of a particle does not necessarily
mean that its acceleration is zero
(4) If speed of a particle is constant, its
acceleration must be zero​

Answer 1

Answer:

opt4 is ans

Explanation:

speed, that is the magnitude of velocity, is constant, whereas the direction of velocity changes, we cannot say that velocity is constant. Therefore, the particle has non-zero acceleration.
