Question

The graph above represents the velocity of some subatomic particle in an electric field. The graph represents the particle' s velocity as its moves in a straight line in positive and negative directions.
During which of the labeled time intervals is the particles slowing down during the entire interval?

• A. $1$ only
• B. $4$ only
• C. $6$ only
• D. $1$ and $4$ only
• E. $1$ and $6$ only

Answer 1

The correct option is A $1$ only

In interval $1$ it is clearly seen that graph is going to Zero velocity from negative velocity. It means magnitude of velocity is decreasing.So particle is slowing down in interval $1$.

All other intervals have either increasing velocity or increasing then decreasing .
