Question

Observe the below mentioned figure and calculate $x$ in such a way that the seesaw would be in equilibrium.

• A. 5

Answer 1

The correct option is A 5

$\text{Moment = Distance from pivot}\times \text{Force}$
$\therefore$ Moment produced by A:
= $500N\times 3m=1500Nm$
For See-Saw to be in equilibrium both moments should be equal
Moment produced by B = Moment produced by A
$\Rightarrow$$x\times 300N=1500Nm$
$\Rightarrow$$x=5m$
