Q. If the over-bridge is concave instead of being convex, the thrust on the road at the lowest position will be

$m g + \frac{m v ^{2}}{r}$

$m g - \frac{m v ^{2}}{r}$

$\frac{m ^{2} v ^{2} g}{r}$

$\frac{v ^{2} g}{r}$

Thrust at the lowest point is $N$
$N = F_{P} + m g$
$N = m g + \frac{m V ^{2}}{R}$

Q. If the over-bridge is concave instead of being convex, the thrust on the road at the lowest position will be

mg+rmv2​

mg−rmv2​

rm2v2g​

rv2g​

Thrust at the lowest point is N N=FP​+mg N=mg+RmV2​

$m g + \frac{m v ^{2}}{r}$

$m g - \frac{m v ^{2}}{r}$

$\frac{m ^{2} v ^{2} g}{r}$

$\frac{v ^{2} g}{r}$

Thrust at the lowest point is $N$
$N = F_{P} + m g$
$N = m g + \frac{m V ^{2}}{R}$
