How much work is needed to assemble an atomic nucleus containing three protons (such as li) if we model it as an equilateral triangle of side 2.00×10−15m2.00×10−15m with a proton at each vertex? assume the protons started from very far away.

The electric potential v is constant everywhere within a certain region of space. which statement below is true? the choices are: the electric field is also constant (but not zero) within the region. a charged particle placed within the region will experience an electric force. the electric field is zero everywhere within the region. the electric field varies from place to place within the region.
