Question

q1 to q3 is 20.0mm and q2 to q3 is 10.0mm on striaght line and q1 is -4.00pc q2 is -6.00pc and q3 is 1.00pc find the net electrostatic force on q2, in n due to q1 and q3

Answer 1

Hence the total force is equal to

(2.4-0.6)∙10^-10=1.8∙10^-10 N
This force is directed to the right, se figure.
