An ice block on a frictionless path starts at rest and is released on the path. At the top of the path the block obviously has GPE how much GPE does it have at point A when it starts at rest? an ice block on a frictionless path starts at rest and is released on the path. How much kinetic energy does it have at point A?

an ice block on a frictionless path starts at rest and is released on the path. How much KE does it have at point B?

An ice block on a frictionless path starts at rest and is released on the path. How high will it go (vertically) as it appoaches point C?​

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
