Now, find the concentration of htions to oh-ions listed in table b of your student guide for a solution at a ph = 11. then divide the ht concentration by the oh- concentration. record these concentrations and ratio in table c what is the concentration of h+ ions at a ph = 11? mol/l what is the concentration of oh-ions at a ph = 11? mol/l what is the ratio of h* ions to oh-ions at a ph = 11? 1, or 1 ) intro done

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
