Question

A particle is performing circular motion in a cicule of radius R find the ratio of displacement of the particle to the distance coverd by it during its 5 complete revolutions

Answer 1

for 5 complete revolutions,

displacement = 0
distance = 5 x 2πR

so,

$\frac{dispacement}{distance \: covered} = 0$
ratio = 0: 10πR = 0
