Regular Physics Question: Superposition Principle

Question

Hi,

I have been given this problem to solve in Physics class regarding the Superposition Principle and Coulombs' Law. If someone could walk me through step by step how to solve this problem, that would be great.

Here is the problem:

In 1919 in Germany, a train of eight kites was flown 9740 m above the ground. This distance is 892 m higher than Mount Everest. Consider the arrangement of charges located at the various heights shown below. If q1 = 2.80 mC, q2 = −6.40 mC, and q3 = 48.0 mC, find the magnitude and direction of the resultant electric force acting on q1.

Thanks!

Answer 1

would you provide the distance between the charges?
