5. Collect data: Select the DESCRIPTION tab. On the SIMULATION pane, turn on Show mass. This lists the total mass of the cart. Each fan exerts a force of 4.0 newtons (N). One newton is the force required to
accelerate a 1-kg object at a rate of 1 m/s?.
For each combination, record the total force, total mass, and acceleration. On the last column, multiply the
mass (m) and acceleration (a).

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
