ELECTROSTATIC FORCE

Name types of electric charge.

Why this situation happen?

Three point charges are alligned along the x-axis as shown in the figure. Find the electric field at the position x=2.0 m, y=0.

• 12.1 N/C

• 20.5 N/C

• 24.2 N/C

• 52.9 N/C

Explain the interaction occur between the charges.

Three charges are arranged as shown in figure. Find the magnitude and direction of the electrostatic force on the charge at the origin.

• 1.35 x 10^-5 N ; 77.5º above negative x-axis

• 3 x 10^-6 N ; 77.5º below negative x-axis

• 1.38 x 10^-5 N ; 77.5º below negative x-axis
