Question
A particle is attracted toward the origin by a force proportional to the cube of its distance from the origin. How much work is done in moving the particle from the origin to
the point (2,4) along the path = assuming a coefficient of friction between particle and the path?
WT = k
W
V friction = ☐ µh
Net work = WT+ W friction
Hint: Central field equation is = kr³; WT is work against central field
