Three charged objects are placed in a line as shown. 0.40 m 0.40 m -2.0 μα 2.0 μ 3.0 μC The force on the middle object due to the other charges is N. It will start moving to the (left/right).

Three point charges are arranged as shown in the figure below. 5.00 nC -3.00 nC 0.300 m 0.100 m Ⓡ (a) Find the vector electric field that the q = 6.50 nC and -3.00 nC charges together create at the origin. X Your response differs from the correct answer by more than 10%. Double check your calculations. N/C Î + (b) Find the vector force on the 5.00 nC charge. UN Î+ UN Ĵ N/Cĵ

Consider the point charges shown below. What will be the magnitude and direction of the force on the 1.0µC charge if the -2.0µC and -3.0µC charges are held in place? -2.0 με 16.0 cm (+ 12.0 cm 1.0 μC -3.0 µC Part A The magnitude of the force on the 1.0uC will be: nνα ΑΣφ F = N Submit Request Answer Part B The point charge will experience the force at an angle of: Πνα ΑΣφ ?

Three spiders are resting on the vertices of a triangular web. The sides of the triangular web have a length of a = 0.86 m, as depicted in the figure. Two of the spiders (S₁ and S3) have +9.0 μC charge, while the other (S₂) has -9.0 μC charge. a/2 O a/2 (a) What are the magnitude and direction of the net force on the third spider (S3)? magnitude N direction o counterclockwise from the +x-axis (b) Suppose the third spider (S3) moves to the origin. Would the net force on the third spider (S3) be greater than, less than, or equal to the magnitude found in part (a)? O greater than in part (a) O less than in part (a) O equal to the part (a) (c) What are the magnitude and direction of the net force on the third spider (S3) when it is resting at the origin? magnitude N direction o counterclockwise from the +x-axis
