PART A) Find the work required by an external agent to bring (at a constant speed) the charge g1 from infinity to the origin (at point P). The electric potential is OV infinitely far away. The distance is d = 5 cm. • The fixed charges are equal to Q₁ = 6C and Q₂ = -2C. • The probe charge is equal to q₁=0,4nC Q. + d D 9₁ d Q₂ Joules PART B) What is the work done by the electric field during the whole process? Joules PART C) Find the work required by an external agent to bring (at a constant speed) the charge g₁ from infinity to the origin (at point P), if the charge Q₂ in part A) was equal to -6C instead. Explain. Joules
Two metal spheres of same size are charged to -12nC and -9nC. If you bring the two spheres in contact. What would be the charge of each spheres after they touched in nC? nC If the sphere to the right was initially positively charged to 12nC instead of -9nC. What would be the net charge after they touched? The ball to the left is still -12nC. nC
6 conductors with cavity are represented here. The net charges inside the middle sphere and the net charges of the hollow sphere conductor are written on the pictures. For each situation A,B,C,D,E and F. Find either the total charge within the dashed lines, the amount of charge at the external surface of the conductor (exterior surface) or the amount of charge at the surface of the internal cavity (interior surface).
