Problem 1 A uniformly charged rod AB has a length L and an unknown negative charge density λ . Two given positive charges Q and 2Q are located at the points C and D, as shown on the Figure 1. Find the value of λ if | AC | = | BD | = L 2 and it is known that the total electrostatic force acting on the charge Q is zero. 2
Problem 2 A uniformly charged insulating spherical shell has the internal and external radii R and 2 R and the volume charge density ρ , as shown on the Figure 2. Find the potential difference Δ V OA = V A - V O between the points O and A if | AO | = 3 R . 3
