Question

The force exerted by the floor of an elevator on the foot of a person standing there is more than the weight of the person if the elevator is -

$\left(a\right)$ Going up and slowing down
$\left(b\right)$ Going up and speeding up
$\left(c\right)$ Going down and slowing down
$\left(d\right)$ Going down and speeding up

• A. $a,b$
• B. $a,c$
• C. $b,c$
• D. $b,d$

Answer 1

The correct option is C $b,c$

The force exerted by the elevator on the foot of a person standing is more than the weight of the person when the direction of acceleration of the elevator is in the upward direction.

Here, in case $b$ and in case $c$, the direction of acceleration of the elevator is upwards.

Hence, option $\left(C\right)$ is the correct answer.
