Question

Three electric charges are arranged on a straight line as shown in the fiqure. 3 False: I Cn is positive, v io neyanive aneren ts negative, then Q2 MUST feel a net force to the right. Select True or False for the following False: If Q1 is positive, Q2 is negative and Q3 is negative, then Q2 MUST feel a net force to the right. False: If Q1 is positive, Q2 is negative and Q3 is positive, then Q2 MUST feel a net force to the right. True: If Q1 is negative, Q2 is negative and Q3 is positive, then Q2 MUST feel a net force to the right. True: If Q1 is positive, Q2 is negative and Q3 is positive, then Q2 MIGHT feel a net force to the right. You are correct. Previous Tries In the above figure, R-1.50 m, Q1-1.57x10-6 C, Q2-1 and Q3--Q1. Calculate the total force on Q2 Entertvour response as positive if the force is to the right and negative if the force is to the left. Subnmit Answer Incorrect. Tries 3/6 Previous Tries 19.72 104-3 N Use Coulomb's Law and superposition of electric forces

Answer 1

The force acting on the charge are kgg. 9x109)(1.57x10-6)(-1.57x10-6 9.8596x10-3 N kQ,9, 72 32 9x10 (1.57x10(1.57x10) 9.8596x103 N The net force acting on the charge is, --9.8596x103-9.8596x103 -0.0197N 一一0.020N The net force acting on the charge is 0.020N The direction is towards left
