Question

This is one question - Please correct the following answers. Thanks.

Three point charges are arranged in a horizontal line as shown below. Find the electric forces (in units of kQ2/R2) on the charges given the following: Q1-45 Q, Q2 r1 3 R, and r22 R. Remember that a positive force points to the right and a negative force points to the left. 4 Q, Q3 =-25 Q, Qs What is the net force on charge Qi? 25 kQ2/R2 The total force on Q1 is going to be a vector sum of F12 (the force on Q1 due to Q2) and F13 (the force on Q1 due to Q3). You need to find both the magnitudes and directions of F12 and F13. The magnitudes of the forces are given by F12 kQ1/r and where k 9e9 Vm/C and the absolute values for all charges should be used The direction of each force is determined by the two charges, where opposite charges attract and same charges repel Submit Answer Incorrect. Tries 1/2 Previous Tries What is the net force on charge Q2? 1.25 kQ2/R2 The total force on Q2 is going to be a vector sum of F21 (the force on Q due to Qi) and F23 (the force on Q2 due to Q3). You need to find both the magnitudes and directions of F21 and F23- The magnitudes of the forces are given by F21 = kQ2Q1/r12 and F23 kQ2Q3/r22, where k 9e9 Vm/C and the absolute values for all charges should be used The direction of each force is determined by the two charges, where opposite charges attract and same charges repel Submit Answer Incorrect.
