A point charge 9 = 3.65 nC is located on the x-axis at I = 2.00 m, and a second point charge q2 = -6.85 nC is on the y-axis at y = 1.20 m. Part A What is the total electric flux due to these two point charges through a spherical surface centered at the origin and with radius r, = 0.345 m? Express your answer in newton times meters squared per coulomb. N- m2 /C • Part B What is the total electric flux due to these two point charges through a spherical surface centered at the origin and with radius r2 = 1.70 m? Express your answer in newton times meters squared per coulomb. ? N- m² /C

answer please v

An uncharged nonconductive hollow sphere of radius 14.0 cm surrounds a 18.0 µC charge located at the origin of a cartesian coordinate system. A drill with a radius of 1.00 mm is aligned along the z axis, and a hole is drilled in the sphere. Calculate the electric flux through the hole. N•m²/C

Conducting Sphere 6 v.A If a total charge of +9.6 C accumulates on the inner surface of the hollow sphere (i.e. the cavity wall), what must be the charge Q of the enclosed point charge? Enter the numerical value in SI units. Type your answer... 7 metal What is the direction of the electric field at point P? A point charge Q is located in an enclosed cavity within a hollow conducting metal sphere. The region in the cavity between the point charge and the sphere is empty space. Point P is completely within the metal. O The electric field at point P is zero. O The direction depends on the value of the charge on the outer surface of the sphere.
