sphere normal vector
A sphere is oriented with an outward pointing normal vector so that its outside is the positive side. , In order to work with surface integrals of vector fields we will need to be able to write down a formula for the unit normal vector corresponding to ..., For a sphere, the surface normal is exactly your P(ϕ,θ), since the normal is just the vector from the origin. Your vector →N is indeed normal to ...,,If it intersects at the point (x,y,z) and the centre of the sphere is at (l,m,n) ... Since you''re finding the normal to a sphere, you just need a vector ... , So you don't want any normal vector, you want a particular one. Actually, since you're taking the length at the end of the day, you want a ..., In more general case for x2+y2+z2=R2 we have n1∥n2 are parallel and both are two normal vectors to the surface with the difference that →n1 ...,But I thought the magnitude of the unit vector is a scalar, in which case ... I believe the top equation is the normal for a general sphere of radius ...
