Two point charges are fixed on a horizontal line 0.30 m apart. Charge \(q_{1}=+8\ \mu\text{C}\) is at the left end and charge \(q_{2}=-2\ \mu\text{C}\) at the right end. (a) Find the magnitude and direction of the net electric field at the midpoint between the charges. (b) A test charge of \(+1\ \mu\text{C}\) is moved slowly from point \(P\) located \(0.20\ \text{m}\) directly above the left charge to point \(Q\) located \(0.20\ \text{m}\) directly above the right charge, along a horizontal path. Calculate the work done by an external agent in moving the test charge from \(P\) to \(Q\) against the electric field. Give your answer in joules to two significant figures.

Answer Options

A. (a) 2.4\times10^{6}\ \text{N C}^{-1} to the left; (b) 0.15\ \text{J}
Correct Answer B. (a) 2.4\times10^{6}\ \text{N C}^{-1} to the right; (b) 0.20\ \text{J}
C. (a) 1.6\times10^{6}\ \text{N C}^{-1} to the left; (b) 0.35\ \text{J}
D. (a) 3.0\times10^{6}\ \text{N C}^{-1} to the right; (b) -0.20\ \text{J}
