Homework Statement
By what angle, in seconds of arc, will a plumbline be pulled out of its normal vertical direction by the gravitation attraction of a 10-ton that parks 20 ft away? Do you think that this effect could be detected?
Homework Equations
I think (G*m1*m2)/r^2
The Attempt at a Solution
[/B]
I first converted 10 tons to Newtons which i got to be around 88964 Newtons (from some conversion website).
then i divided 88964 by 9.8 to get 9077.96 kg for the truck.
20 ft becomes 6.096 meters.
Plugging this into the equation, I get
(G * (m(plumb) * 9077.96 kg))/(6.096 m)^2
I don't know how to find the mass of the plumbline.
