Question

The displacement-time graphs of two moving particles make angles of $30 degree blank a n d blank 45 degree$ with the $x minus$ axis. The ratio of their velocities is

$1 : \sqrt{3}$
$1 : 2$
$1 : 1$
$\sqrt{3} : 2$

The correct answer is: $1 blank colon blank square root of 3$

Slope of displacement time-graph is velocity
$fraction numerator v subscript 1 end subscript over denominator v subscript 2 end subscript end fraction equals fraction numerator tan invisible function application theta subscript 1 end subscript over denominator tan invisible function application theta subscript 2 end subscript end fraction equals fraction numerator tan invisible function application 30 degree over denominator tan invisible function application 45 degree end fraction equals fraction numerator 1 over denominator square root of 3 end fraction$
$v subscript 1 end subscript blank colon v subscript 2 end subscript equals 1 blank colon blank square root of 3$
