Question

Velocity - time graphs of two bodies A and B are as shown in figure. The ratio of Their acceleration is

• A. $1:3$
• B. $3:1$
• C. $1:\sqrt{3}$
• D. $\sqrt{3}:1$

Answer 1

The correct option is B $3:1$

$\begin{array}{c}{a}_A=\tan {60}^0=\sqrt{3}\\ a_B=\tan {30}^0=\frac{1}{\sqrt{3}}\\ \frac{a_A}{a_B}=3\\ Hence,\\ optionBiscorrectanswer.\end{array}$
