2 min 20 s = 120 s + 20 s = 140 s
140 s / 40 s = 3.5
So, in 2 min 20 s particle covered 3.5 revolutions.
Distance = 3.5 × (2 π r)
= 3.5 × 2 × 22/7 × r
= 22r
After 3 revolutions displacement is zero.
After 0.5 revolution particle is diametrically opposite point
Displacement = 0.5 × 2 π r
= 22r/7
Ratio
Displacement : Distance = 22r/7 : 22r = 1/7 : 1 = 1 : 7
140 s / 40 s = 3.5
So, in 2 min 20 s particle covered 3.5 revolutions.
Distance = 3.5 × (2 π r)
= 3.5 × 2 × 22/7 × r
= 22r
After 3 revolutions displacement is zero.
After 0.5 revolution particle is diametrically opposite point
Displacement = 0.5 × 2 π r
= 22r/7
Ratio
Displacement : Distance = 22r/7 : 22r = 1/7 : 1 = 1 : 7
