medium
આકૃતિમાં દર્શાવ્યા મુજબ એક પદાર્થનો વેગમાન $p$ એ સમય $(t)$ ની સાપેક્ષે બદલાય છે. તો તેને અનુરૂપ બળ. $(F)$ - સમય $(t)$ નો ગ્રાફ ક્યો છે

D
Solution
(a)
$F=\frac{d p}{d t}=$ slope of $P-t$ curve
From $t=0$ to $t=2$ second slope is constant and positive
From $t=2$ to $t=6$ second slope is zero
From $t=6$ to $t=8$ second slope is constant and negative
$F=\frac{d p}{d t}=$ slope of $P-t$ curve
From $t=0$ to $t=2$ second slope is constant and positive
From $t=2$ to $t=6$ second slope is zero
From $t=6$ to $t=8$ second slope is constant and negative
