A) An isolated spherical conductor has an excess charge of -9.8Î¼C placed on its surface. Inside the conductor is a cavity, withinwhich is a point charge of 4.10 Î¼C. How many excess electrons areon the exterior surface of the conductor?
B) A cubical box has a charge q = -2.1 Î¼C placed at its center.Calculate the electric flux through the right face of the box.
C) A charged ball with a mass of 10.0 g is suspended on a stringin a horizontal electric field of 150.0 N/C directed to the right.The string makes an angle of 13.0 deg to the right of vertical.Find the charge carried by the ball.
D)Two charges, q₁ = -16.5 Î¼C and q₂ = -1.5Î¼C , are located at (x,y) = (13.2, 22.2) cm and (10.6, 16.4) cmrespectively. Find the electrostatic force between these twochanges (take an attractive force to be negative)
