An airplane with a mean-aerodynamic chord of 6ft. when fully ‘loaded’ with 100 passengers, each carrying 20lb baggage, has a static margin of 0.15. the total weight of the aircraft is 20,000lb. determine the change in the static margin if the each passenger carries an additional 20lb of baggage. make the following assumptions: the total baggage is treated as point-mass and is always located at 24ft. behind the neutral point; the only ‘extra’ weight is the additional baggage.

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
