Problem
Three point charges X, Y and Z are fixed at the corners of an equilateral triangle. A qualitative field-line sketch shows the following counts:
• 12 lines originate from X and terminate on other charges.
• 18 lines enter Y from outside and end there.
• 6 lines enter Z from outside and end there.
(i) State the algebraic sign of each charge.
(ii) Arrange the magnitudes ∣QX∣,∣QY∣,∣QZ∣ in ascending order.
