Question

a body moves on a circular distance of radius R starting from a point A the moves to a point B which is on the other and end of the dimeter AB the ration of the distance traveled to the displacement made by him is

​

Answer 1

Answer:

π/2

Explanation:

Diameter = AB

Distance = 2πr/2= πr

Displacement = r +r = 2r

Dist/ Displacement=πr/2r =π/2

Answer 2

Answer:

11:7

Explanation:

2πr/2= 2×22/7×R/2

= R22/7= Distance travelled buy him

Diameter= Displacement=AB= R×2=2R

Ratio of distance to displacement=R22/7/2R

=R22/7×2R

=R11/7R

=11/7=11:7
