Worksheet: Chapters 17 A solid metal sphere of radius R 1 = 50 cm has a charge of +2.0 μ C. 1) What is the strength of the electric field at the center of the sphere? 2) What is the maximum strength of the electric field caused by the sphere? Where is it found? 3) What force would act on an excess electron ( q = -1.60 x 10 -19 C) on the surface of the sphere? 4) What is the strength of the electric field at a point 60 cm from the center of the sphere? 5) What force would act on an alpha particle ( q = +3.20 x 10 -19 C) located 60 cm from the center of the sphere? A point charge + q is located at x = 1.0 m. A second point charge –3 q is located at x = -1.0 m. 6) Determine the electric field strength for x < -1 in terms of q , x , and fundamental constants. 7) Determine the electric field strength for –1 < x < 1 in terms of q , x , and fundamental constants. 8) Determine the electric field strength for x > 1 in terms of q , x , and fundamental constants. 9) What is the x -coordinate of the point at which the net electric field is equal to zero?
