9. Make a small dipole by bringing the two charges very close to each other, where they are barely touching. The midpoint of the two charges should still be on one of the grid point intersections (see figure below). Measure the strength of the electric field 0.5 m directly above the midpoint as well as 1 m directly above. Question-11: Does the strength of the electric field decrease as 1/r2? Yes, the strength of the electric field decreases as 1/r"2 Question-12: The electric field 2.3 cm from a very small, charged object points away from the object with a magnitude of 290,000 N/C. What is the charge on the object? Show your calculation. The charge on the object is calculated to be 2.0 pC Question-13: Two point charges of 20 pC and -33 puC are separated by a distance of 15.0 cm. What is the magnitude of electric field due to these charges at a point midway between them? Show your calculation
