A single-turn current loop, carrying a current of 5.82 A, is in the shape of a right triangle with sides 43.4, 115, and 123 cm. The loop is in a uniform magnetic field of magnitude 106 mT whose direction is parallel to the current in the 123 cm side of the loop. What is the magnitude of the magnetic force on (a) the 123 cm side, (b) the 43.4 cm side, and (c) the 115 cm side

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
