Question

If $\theta$ is angle between the velocity and acceleration of a particle moving on a circular path with decreasing speed, then

• A. $\theta=90^{\circ}$
• B. $0^{\circ}<\theta<90^{\circ}$
• C. $90^{\circ}<\theta<180^{\circ}$
• D. $0^{\circ} \leq \theta \leq 180^{\circ}$

Answer 1

Answer: (C)

$\theta$ between $v \& Q$ is $90^{\circ}<\theta<180^{\circ}$
