Question

An electron revolves around the nucleus of an atom in a circular orbit of radius 'r'. Calculate the distance and displacement when electron completes (a) 1/2of the orbit (b) 3/4 of orbit (c) 1 complete revolution.

Answer 1

(a) distance 1/2(2*pie*r)
displacement 2r
(b)distance 3/4(2*pie*r)
displacement =r
(c) distance 2*pie*r
displacement =0
