Question

Three point charges lie along a straight line as shown in the figure below, where q₁ = 6.48 µC, q₂ = 1.42 µC, and q₃ = -2.08 µC. The separation distances are d₁ = 3.00 cm and d₂ = 2.00 cm. Calculate the magnitude and direction of the net electric force on each of the charges.

Three charges lie along a horizontal line. Positive charge q₁ is on the left. Positive charge q₂ is a distance d₁ to the right of q₁. Negative charge q₃ is a distance d₂ to the right of q₂.

(a) q₁

magnitude	N
direction	---Select--- to the left to the right

(b) q₂

magnitude	N
direction	---Select--- to the left to the right

(c) q₃

magnitude	N
direction

Answer 1

Lets consider the force directing towards the left side as negative denoted by and the force directing towards the right side be positive denoted by

Page3

Hence, the net electric force on

charge q₁ is of magnitude 43.49 N directing to the left side of the charge

charge q₂ is of magnitude 158.472 N directing to the right side of the charge

charge q₃ is of magnitude 115.16 N directing to the right side of the charge
