Practice Problem 19.48 Mastering Physics

The question says:

The electric field between the plates of a parallel-plate capacitor is horizontal, uniform, and has a magnitude E. A small object with a charge of -2.12 is attached to the string. The tension in the string is 0.310 , and the angle it makes with the vertical is 12 .

What is the mass of the object?

What is the magnitude of the electric field?


Not sure where to even begin here.... help?

Instructions

Instructions on how to ask and leave feedback on the blog:
1. Each post that is made by anyone should be a separate question. For example, if someone posts "I don't know how to do #3 on the homework" don't reply to them by adding another post REPLY BY LEAVING A COMMENT! This way each question will have its own post.

2. When you post something choose the "Compose" tab NOT the "Edit HTML" tab!

3. Each time you post a new question there should be a text box on the bottom left of the posting window called "Label". Write in either the question # or a small description of the question you are asking so other people can find it if they search. For example: Assignment #3 "Two point charges" or Ch.19 Problem #3

4. If you are writing a post about a masteringphysics homework question be sure to write the NAME of the question along with both the assignment number and which part (A,B,ect.) in the "Labels for this post" text box

Thanks guys,
