Homework Statement
Three ions, each with a charge Q = e, located at the corners of an equilateral triangle with
side length r midpoint of one of the sides of the triangle described M.
a) Calculate the magnitude and direction of the electric field E of the three ions generated at point M.
Size E is expressed by the symbols e and r addition, the value of E is calculated when
r=1,2*10-10m
b) Calculate the electric potential V at point M. Size V must be expressed by the symbols e and r
In addition, the value of V is calculated as r=1,2*10-10m.
The Attempt at a Solution
a) I know that the electric field is a vector which is the vector sum of all the sources contribution, but I find it hard to express it.
b) I know that the potential is a scalar size (ie without direction) whose value is the sum of all sources contributions.
Can someone help please?
