NEET Physics Motion In A Straight Line MCQs

🔄Ncert Concepts :Average Velocity, Displacement, Circular Motion

A body moves in a straight line for time $t_1$ with velocity $v_1$ and for time $t_2$ with velocity $v_2$ in the same direction. If the average velocity is equal to $(2v_1v_2)/(v_1+v_2)$ , then the condition relating $t_1$ and $t_2$ is:

$\frac{t_1}{t_2} = \frac{v_1}{v_2}$

$\frac{t_1}{t_2} = \frac{v_2}{v_1}$

$t_1 = t_2$

$t_1v_1 = t_2v_2^2$
