18.1.3—An electric field by means of field lines question 1

[Maximum number: 2]

An isolated conducting sphere in a vacuum has a capacitance of 69 pF . The charge on the sphere is +83 pC .

On Fig. 6.1, draw field lines to represent the electric field outside the sphere due to the charge on the sphere.
