question 55

Multiple Choice

As shown in the figure, three charges are at the vertices of an equilateral triangle. The charge Q is 6.7 nC, and all the other quantities are accurate to two significant figures. What is the magnitude of the net electric force on the charge Q due to the other two charges? (k = 1/4πε₀ = 9.0 × 10⁹ N ∙ m²/C²)

• A)2.1 × 10^-3 N
• B)1.2 × 10^-3 N
• C)1.0 × 10^-3 N
• D)1.4 × 10^-3 N
