Question
A-2.0 nC charge and a 2.0 nC charge are located on the r-axis at x = -1.0 cm and a = +1.0 cm, respectively. At what position or positions on the a-axis is the electric field zero? O x = -2.0 cm O x = 0 O x = +2.0 cm O x = too Part B At what position or positions on the r-axis is the electric potential zero? O x = +2.0 cm O z = 0, to0 O x = +00 O x = -2.0 cm

Expert Solution
Step 1

X1 = -1.0cm 

X2 = 1.0 cm 

Q1 = -2 nC

Q2=  2nC 

For electric field to be zero,

For like Charge ,at their mid point 

For unlike charge of different magnitude, at closer to weaker charge.

For unlike and same magnitude, no zero point between them or away from them..
