What is the distance between the two charges? (3sf and units) 2. In what region(s) is the electric resultant electric field zero? 3. If the distance from Q1 to the closest point, where E is zero, is taken to be x, what are r1 and r2? 4. Calculate the value of x. 5. The position coordinate of this point, where E is zero along the x-axis, is1. Two 1-C negatively charged objects lie along a line as shown. The x's marked B and D lie along a line that is half way between the two charges. For locations A, B, and C, draw force diagrams for a positive test charge at those locations in the boxes provided. Make sure you get the relative lengths of the force vectors correct. Location A Ax Bx C Ꭰ * E x Location B Location C On the diagram, draw an arrow for each of the five locations marked with an x that shows the direction of the electric field at that location. If the electric field is zero at any location, state that explicitly. Suggestion: use the force diagrams for the test charge, and add the forces using the head-to-tail method.▼ Part A What is the magnitude of the electric field at a point midway between a –7.4 µC and a +8.2 µC charge 9.8 cm apart?
