E field of a sphere

WebAny conservative field can always be written (up to a constant) as the gradient of some scalar quantity. This holds because the curl of a gradient is always zero. For the conservative E-field one writes: (The –ve sign is just a convention) E =−∇φ r Then ∇×(F)=∇×(∇ϕ)=0 r F =∇ϕ r If Where φis the scalar electric potential WebFeb 8, 2010 · Homework Statement.
