Find the Electric Force on q₄ given the following charges: q_(1)=4.0E-6C, q₂=-4.0E-6C, q₃=3.0E-6C, q₄=3.0E-6C and the distance x=2.0cm. (b) Find the Electric Potential at point pq_(1)=4.0E-6C,q₂=-4.0E-6C,q₃=3.0E-6C,q₄=3.0E-6Cx=2.0cm?
a. Calculate the electric force using Coulomb's law formula F = k * |(q1 * q4) / (x²)|, where k is the Coulomb constant
b. Calculate the electric force using the formula F = q4 * E, where E is the electric field at the location of q4
c. Calculate the electric potential using the formula V = k * (q1 / x + q2 / x + q3 / x + q4 / x), where k is the Coulomb constant
d. Calculate the electric potential using the formula V = k * (q1 / x + q2 / x + q3 / x - q4 / x), where k is the Coulomb constant
