A pollen particle, treated as a point object, possesses a mass of 0.3 kg and is situated within a uniform electric field of 0.2 N/C directed vertically upward. The pollen particle experiences an upward acceleration of 15 m/s². Given the gravitational acceleration of g = 9.8 m/s², what is the charge Q on the pollen particle (unit in C)?

A +5×10-9 C point-charge is in static equilibrium at the center of a conducting spherical shell, which has an inner radius of 0.3 m and an outer radius of 0.5 m. The shell itself carries a net charge of -6×10-9 C. What is the magnitude of the electric field immediately outside the outer surface of the shell, with unit in N/C? Note that magnitude is positive.

Consider a prism-shaped object with the following dimensions: AD = 0.5 m (height), DF = 0.2 m (depth), and AB = 0.6 m (length). AD is perpendicular to DF. The prism is fully immersed in a uniform electric field of magnitude 200 N/C, directed parallel to the z-axis (DA direction). What is the electric flux out of the face ABEF?  The unit of electric flux is N∙m2/C2.
