A charged object produces an electric field strength of magnitude N/C at a distance of 2.6 m from its center. Find the charge of the object. Use N⋅m2/C2 for the value of Coulomb’s constant. Answer to three decimal places.
An object with a charge of 1.5 C is at a point in an electric field where the field strength is 12 N/C. What is the magnitude of the force on the object?
An object has a charge of 0.335 nC. At a point near the object, the strength of the electric field from the object has a magnitude of 5.65 N/C. Find the distance from the object to the point. Use N⋅m2/C2 for the value of Coulomb’s constant. Give your answer to one decimal place.
