Question

Charged insulated sphere with R=1.5 cm equally spread charge Q=2.6 nC is located in the middle of the coordinate system (midle of the sphere). In x= L= 10 cm is dot charge q =-2.1 nC.

a) Calculate total electrical potential because of the sphere and the dot charge at point x₁ = 5.0 cm and x₂ = 1.5 cm

b) Calculate total electric field because of the sphere and the dot charge at point x₁ = 5.0 cm and x₂ = 1.5 cm

c) Sample charge q₀ =-1,8 nC with mass m=1.5*10^-9 kg is held stationary in x= 5.0 m and then released. Find the speed of q₀ when it lends on the sphere.
