Dos esferas de masas m1=0,3gr y m2=0,6gr tienen cargas iguales, están colgadas de un punto en comun. El angulo de separación entre los hilos es de 18° y con una longitud de los hilos de 0,2m calcula: a) cuelgan simétricamente las dos esferas, o son diferentes los ángulos entre la vertical y cada uno de los hilos? Calcule el o los ángulos b) calcule la carga neta de cada esfera

To understand the electric potential and electric field of a point charge in three dimensions consider a positive point charge q, located at the origin of three-dimensional space. throughout this problem, use k in place of 14? ? 0. part adue to symmetry, the electric field of a point charge at the origin must point from the origin.answer in one word.part bfind e(r), the magnitude of the electric field at distance r from the point charge q.express your answer in terms of r, k, and q. part cfind v(r), the electric potential at distance rfrom the point charge q.express your answer in terms of r, k, and q part dwhich of the following is the correct relationship between the magnitude of a radial electric field and its associated electric potential ? more than one answer may be correct for the particular case of a point charge at the origin, but you should choose the correct general relationship. a)e(r)=dv(r)drb)e(r)=v(r)rc)e(r)=? dv(r)drd)e(r)=? v(r)r
