Answer 1

To pull the cork out of the wine bottle with a cork opener the moment due to both the force must be equal i.e.,

$F_c\times9=(9+70)\times F$

F_c is the force required to pull the cork out of the top of the wine bottle.

$\therefore\ 9F_c=79F$

$or,\ F=\frac{9}{79}F_c$

Range of F_c is 200 to 430 N .

So range of F is:

$F_{min}=\frac{9}{79}\times200\ N=22.78\ N$

$F_{max}=\frac{9}{79}\times430\ N=48.99\ N$
