What is the magnitude e of the electric field at point p? throughout this part, express your answers in terms of the constant k, defined by k=14ïïµ0. express your answer in terms of l, î», d, and k?

The strength of the electric field is generally equal to 

E = F/Q

However, this could be modified in terms of charge and distance,d.
E = kQ/d²
The k is actually a constant which is equal to 1/4π∈₀

Since no given quantitative data, the answer should just be E = kQ/r².

B) as the temperature increases, the kinetic energy of the particles increases.|-/
