should not be used in calculating for other values because it is already rounded off and might affect your answer. What is the magnitude of the electric field due to this sphere at a point 5cm outside the sphere's surface? What is the direction of the electric field at point 5cm outside the sphere's surface? What is the magnitude of the electric field due to this sphere at a point 5cm from the center of the sphere? What is the direction of the electric field at point 5cm from the center of the sphere?

A uniformly charged disk has radius 2.50 cm and carries a total charge of 6.0x 10-12 C .(Figure 1) Find the magnitude of the electric field on the z-axis at z = 20.0 cm Find the direction of the electric field on the a-axis at z = 20.0 cm. Is the magnitude of the electric field you calculated in part A larger or smaller than the electric field 20.0 cm from a point charge that has the same total charge as this disk? What is the percent difference between the electric fields produced by the finite disk and by a point charge with the same charge at a = 20.0 cm? dEx dp

03. The distance between two charges q1 = + 2 μC and q2 = + 6 μC is 15.0 cm. Calculate the distance from charge q1 to the points on the line segment joining the two charges where the electric field is zero. Express your answer in cm with 3 - significant figures.
