Kramer goes bowling and decides to employ the force of gravity to "pick up a spare." He rolls the 5.00 kg bowling ball very slowly so that it comes to rest a center-to-center distance of 0.140 m from the one remaining 1.25 kg bowling pin. Treat both the ball and the pin as point objects, and determine the magnitude of the force of gravity Fgrav between them.

The frequencies refer to the sample data collected from a population of interest when performing a hypothesis test comparing two or more population proportions.

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
