How far can the remote control extend without tipping over?

Homework Statement

A .110-kg remote control 21.0cm long rests on a table, with a length L overhanging its edge. To operate the power button on this remote requires a force of .365N. How far can the remote control extend beyond the edge of the table and still not tip over when you press the power button? Assume th3e mass of the remote is distributed uniformly, and that the power button is on the end of the remote overhanging the table.

Homework Equations

No idea.

The Attempt at a Solution

None

 

[th4450]

Take moment about the edge of the table.
No net moment in equilibrium, i.e.
clockwise moment = anticlockwise moment

 

[mmajames]

What moment? Moment of inertia?

 

[th4450]

$\tau$ = Fd$_{\bot}$
where d$_{\bot}$ is the perpendicular distance between the pivot (edge of the table) and the force

 

[mmajames]

So how would I set up the equations?

Clockwise moment = W·d
Anticlockwise moment = F·d
