Three Point Charges Are Arranged In A Horizontal Line As Shown Below Find The Electric Forces In Units Of Kqp R2 On T 1 (50.53 KiB) Viewed 40 times
Three point charges are arranged in a horizontal line as shown below. Find the electric forces (in units of kQP/R2) on the charges given the following: Q1 = 4 Q, Q2 = 12 Q, Q3 = -48 Q, 11 = 2 R, and r2 = 2 R. Remember that a positive force points to the right and a negative force points to the left. What is the net force on charge Qz? kQ²/R? Submit Answer Tries 0/2 What is the net force on charge Q2? kQ²/R? Submit Answer Tries 0/2 What is the net force on charge Q3? KQ?/R? Submit Answer Tries 0/2 What is the sum of the forces on all three charges? kQ²/R?
The picture shows the field lines of a nonuniform electric field and five points A to E in the field. Consider the following statements. Which one is true? The electric field strength at point A is zero because there is no electric field line passing through this point. The electric field strength at point C is larger than at point B. This electric field may be due to a negatively charged object located to the left. We cannot compare the electric field strengths at points E and C because they are not drawn on the same electric field line. The electric field strengths at points A and D are both zero because there are no electric field lines on them. Submit Answer Tries 0/2
