In Johnny’s Physics class, they were tasked to think and suggest a way to make a stainless-steel spoon float on water using the following materials only –stainless steel spoon, a container of water, and a supply of olive oil. Jim, who is Johnny’s groupmate, suggested to coat the spoon with olive oil. Jim reasoned that this would work since olive oil is less dense than water, the spoon will float on the surface of the water with the olive oil.

Hearing Jim’s explanation, Johnny was doubtful if Jim’s suggestion would really work.

If you were Johnny’s groupmate, using your understanding of the Physics you learned, write an explanation whether Jim’s suggestion would work or not.

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
