(Question 1 of 3) Three-point charges, +5.7 µC, +1.3 µC, and −3.2 µC, lie along the x-axis at 0 cm, 1.6 cm, and 5.4 cm, respectively. What is the force exerted on q1 by the other two charges? (To the right is positive.) The Coulomb constant is 8.99 × 109 N · m2 /C 2 . Answer in units of N.

(Question 2 of 3)What is the force exerted on q2 by the other two charges? (To the right is positive.) Answer in units of N.

(Question 3 of 3)What is the force exerted on q3 by the other two charges? (To the right is positive.) Answer in units of N.

What is the force exerted on q1 by the other two charges?

F = - 9e9 * 5.7e-6 * 1.3e-6 / 0.0162 + 9e9 * 5.7e-6 * 3.2e-6 / 0.0542

F = - 260.5 + 56.3

F = - 204 N ( net force is to the left)

What is the force exerted on q2 by the other two charges

F =  9e9 * 5.7e-6 * 1.3e-6 / 0.0162 + 9e9 * 3.2e-6 * 1.3e-6 / 0.0382

F = 260.5 + 25.9

F = 286.4 N ( to the right)

F = - 9e9 * 5.7e-6 * 3.2e-6 / 0.0542 - 9e9 * 3.2e-6 * 1.3e-6 / 0.0382

F = - 56.3 - 25.9

F = - 82.2 N ( to the left)
