a Two large conducting spheres carrying charges 9 and 9 are brought close to each other Is the magnitude of electrostatic force between them exactly given by 9 9 4 where r is the distance between their centres b If Coulomb s law involved 1 r dependence instead of 1 r would Gauss s law be still true c A small test charge is released at rest at a point in an electrostatic field configuration Will it travel along the field line passing through that point d What is the work done by the field of a nucleus in a complete circular orbit of the electron What if the orbit is elliptical
