In this lesson, we will learn how to relate electric forces to electric fields and describe the electric field lines produced by groups of charges.
Students will be able to
Q1:
A charged object produces an electric field strength of magnitude 1.05×10 N/C at a distance of 2.6 m from its center. Find the charge of the object. Use 8.988×10 N⋅m2/C2 for the value of Coulomb’s constant. Answer to three decimal places.
Q2:
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?
Q3:
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 8.988×10 N⋅m2/C2 for the value of Coulomb’s constant. Give your answer to one decimal place.
