1) Two identically charged objects exert a force of 4.0 N when they are placed 75 cm apart. What is the magnitude of the charge on each object?

2) Attached file

3) A -4.5 ?C charge experiences a force of 3.80 N to the right. What is the electric field intensity at this point?

4) Sketch the electric field in the vicinity of:

a) a negative source charge

b) two oppositely charged sources

Question 2 (4 points) Two charged objects are located at the vertices of a right-angle triangle as shown. O A= - 5.0 PC 20 om -18 cm - B = +20 HC What is the net field at point X? (Hint charges are important) 99+
