Neco 2019 Physics Question 24
Practice objective / multiple choice question 24 from the 2019 Neco Physics examination.
Two fixed point charges, \(+2\ \mu\text{C}\) at point A and \(-3\ \mu\text{C}\) at point B, are 0.12 m apart. A third charge of \(+1\ \mu\text{C}\) is placed somewhere on the line AB such that the net electric field at its position is zero. (i) Find the distance of the \(+1\ \mu\text{C}\) charge from charge A. (ii) Calculate the electric potential at that point due to the two fixed charges. Give the distance in centimetres (to two significant figures) and the potential in volts (in scientific notation, two significant figures).
