SATHEE: Kinematics Question 342

Kinematics Question 342

Question: The displacement-time graphs of two particles A and B are straight lines making angles of $30^{\circ}$ and $60^{\circ}$ respectively with the time axis. If the velocity of a is $v_{A}$ and that of b is $v_{B}$ , the value of $v_{A} / v_{B}$ it’s

Options:

A) $\frac{1}{2}$

B) $\frac{1}{\sqrt{3}}$

C) $\sqrt{3}$

D) $\frac{1}{3}$

Show Answer

Answer:

Correct Answer: D

Solution:

$v_{A} = t a n 30^{\circ}$ and $v_{B} = t a n 60^{\circ}$
$∴ \frac{V_{A}}{V_{B}} = \frac{\tan 30^{\circ}}{\tan 60^{\circ}} = \frac{1 / \sqrt{3}}{\sqrt{3}} = \frac{1}{3}$
