Two Tiny Particles Having Charges Q₁ = +56 $0.500 \mathrm {~m}$

question 111

Short Answer

Two tiny particles having charges q₁ = +56.0 nC and ^q₂ = -46.0 nC are separated by $0.500 \mathrm {~m}$ and held in place, as shown in the figure. A third particle, having a charge of $54.0 \mathrm { nC }$ is placed at the point A, which is 0.18 m to the left of ^q₂. How much work is needed to move the third particle from point A to point B, which is 0.40 m to the left of ^q₁. All the points in the figure lie on the same line. (k = 1/4πε₀ = 9.0 × 10⁹ N ∙ m²/C²)
