This is an example problem from one of my lectures, and I was not sure how they arrive to the solution.
Originally the C23 capacitor, was C2 and C3 capacitors in parrallel. They combined them into Ceq by additing them two.
Yes! Here the set up that gave me the right answerhttps://fbcdn-sphotos-h-a.akamaihd.net/hphotos-ak-xpf1/v/t34.0-12/11014718_10152670767961806_1607350090_n.jpg?oh=c796df67fefef907f1ccfe3fbafe9f57&oe=54ECB140&__gda__=1424800785_7febf55bcb55aca57d3a84e1bb4b6827
Oh, I completely forgot about that, and then it will be Tcosθ, and you find T using the mg=Tsinθ
the euqation there fore will be
F(electrical)- Tsinθ-mgcosθ= 0
and you solve for F(electrical)
F(electrical) = qE
and then you look for q
Is it the force due to the other charge, which will be + and equalt to kq^2 / r^2... and I would find R using sinθSorry, I mized it with other problem.
What other force there could be?
Homework Statement
The tine sphere at the end of the weightless thread has a mass of .60g. It is immersed in air and exposed to a horizontal electric field of strength 700 N/C. The ball is in equlibrium in the position shown. What are the magnitude adn sign of the charge on the ball?
