Question
Three point charges are placed on the $x$ -axis. A charge of $3.00 \mu \mathrm{C}$ is at the origin. A charge of $-5.00 \mu \mathrm{C}$ is at $20.0 \mathrm{cm},$ and a charge of $8.00 \mu \mathrm{C}$ is at $35.0 \mathrm{cm} .$ What is the force on the charge at the origin?
Step 1
We have three charges: $Q_1 = 3.00 \times 10^{-6} C$, $Q_2 = -5.00 \times 10^{-6} C$, and $Q_3 = 8.00 \times 10^{-6} C$. The distances between the charges are $r_{12} = 0.2 m$ and $r_{13} = 0.35 m$. Show more…

Three point charges are positioned on the $x$ -axis: $+64.0 \mu \mathrm{C}$ at $x=0.00 \mathrm{~cm},+80.0 \mu \mathrm{C}$ at $x=25.0 \mathrm{~cm},$ and $-160.0 \mu \mathrm{C}$ at $x=50.0 \mathrm{~cm} .$ What is the magnitude of the electrostatic force acting on the $+64.0-\mu C$ charge?
Point charge A with a charge of +3.00 μC is located at the origin. Point charge B with a charge of +6.00 μC is located on the x axis at x = 7.00 cm. And point charge C with a charge of +2.00 μC is located on the x axis at x = -6.00 cm. What is the net force (magnitude and direction) exerted on charge A by the others?
Three charges are located along the $x$ -axis. Charge $A(+5.00 \mu \mathrm{C})$ is located at the origin. Charge $B(+4.50 \mu \mathrm{C})$ is located at $x=+0.650 \mathrm{~m}$. Charge $C(-4.20 \mu \mathrm{C})$ is located at $x=+0.650 \mathrm{~m}$. Find the total force (and direction) on charge $B$.
