Problem: Calculate the magnitude of the electric field 2.00 m from a point charge of 5.00 mC (such as found on the terminal of a Van de Graaff).

FREE Expert Solution

Electric field:

E=kqr2, where k is Coulomb's constant, is the charge, and is the distance from the charge. 

We know that k = 9 × 109 N•m2/C2
