A rod 12.0 cm long is uniformly charged and has a total charge of -24.0 µC. Determine the magnitude and direction of the electric field along the axis of the rod at a point 36.0 cm from its center. magnitude N/C direction ---Select--- 8

Review | Const Imagine a right angle triangle with two equal sides of 10 cm. Two equal charges of +10μC are placed in the vertices corresponding to the 45° angles. A negative, -20μC charge is placed at the 90° vertex. Find the electric field in the middle of the hypotenuse. You need to provide the magnitude of the field and the direction. For the direction use the angle between the electric field and the hypotenuse (the one less than 90°). Part A - What is the magnitude of the field at the point in the midle of the hypothenuse? μA Units Request Answer Part B - What is the angle between the total field and the hypothenuse? (If the angle is not 90 degress, give the angle which is less than 90 degrees) < Return to Assignment Provide Feedback Value Submit

A Van de Graaff generator is charged so that a proton at its surface accelerates radially outward at 1.32 ✕ 1012 m/s2. Find the following. (a) the magnitude of the electric force on the proton at that instant magnitude  N direction  ---Select--- radially outward radially inward clockwise counterclockwise (b) the magnitude and direction of the electric field at the surface of the generator magnitude  N/C direction  ---Select--- radially outward radially inward clockwise counterclockwise

2. Suppose that charge #1 is positioned at the origin (x = 0 m, y = 0 m) and has a magnitude of +2.6 μC, and that charge #2 is positioned on the y-axis at y = 0.16 m and has a magnitude of -4.3 µC. Find the x- and y-components of the electric field on the x-axis at x = 0.21 m. Also, find the x- and y-components of the force on a charge of +6.3 nC placed at this point (x = 0.21 m).
