Homework Help: Physics PLEASE HELP!

Posted by Adriana on Monday, January 28, 2013 at 11:23pm.

A spring with an unstrained length of 0.076 m and a spring constant of 2.6 N/m hangs vertically downward from the ceiling. A uniform electric field directed vertically upward fills the region containing the spring. A sphere with a mass of 5.09 10-3 kg and a net charge of +6.5 湣 is attached to the lower end of the spring. The spring is released slowly, until it reaches equilibrium. The equilibrium length of the spring is 0.059 m. What is the magnitude of the external electric field?

Answer in N/C

Note: the way my teacher told me to solve it is to use the equation: mg+ kx=qE. I know i have to solve for E but I dont know what to plug in for (g). Any help would be great! Thanks
