Four point charges are equally separated by 1.00 m in air. If q1= 3.0 nC, q2=-4.0 nC, q3=2.0nC and q4=-5.0 nC, what is the electric field at a point halfway between q2 and q3. ( arrangement of the charge: q1,q2,q3,q4). Please include detailed solution for me to understand the problem: Topic: Coulomb's Law, Electrical Field (Physics)

Four charges are distributed around a circle as shown in the figure. The point P is at the center of the circle. The magnitude of the electric field generated by each charge point P is 300 N/C. What is the (a) direction and (b) magnitude of the net electric field at point P? li Q₂ Write your answer the following way: (a) Direction (b) Magnitude (Choose from left/right/up/down); Explanation.......... N/C; Calculation / Explanation:...------

Please answer the following question(s): In the figure below Q₁ +3.0 μC, Q2 =-6.0 μC and Q3 = +2.0 μC. X=0 Q3 Q3 +2 μC Use the applet below to draw a free body diagram of charge Q1. 1. The choices for the force of Q2 on Q1, F2-1, are shown as arrows with the yellow tails. The choices for the force of Q3 on Q1, F31, are shown as arrows with the green tails. If F21 is greater than F3+1 pick the larger vector for F21 and the smaller vector for F31 and vice-vel x = 0 cm F2₂-1 2. Drag and place the two force vectors on Q₁ (blue dot) picking the correct choice for the directi and magnitude of the two forces. F2-1 Q1 x=3cm Select the appropriate directions and relative magnitudes of F2-1 and F3-1 and place their tails on Q₁. F2-1 x = 1 cm F2-1 Q2 x=4cm + x 2 cm Q₁ = +3 µC X x = 3 cm F3-1 F3-1 Q2 = -6 μC x = 4 cm F3-1 F3-1

Both of them, please.
