Question

a body covered a distance of 6 metre along a semicircular path calculate the magnitude of displacement of the body and the ratio of distance to displacement ​

Answer 1

Answer:

Let R be the radius of semi-circular path

Displacement in semi circular path = 2R

distance covered in semi circular path = πR

 

ratio of distance covered to displacement = π/2

Answer 2

Answer:

6metre =22/7×R

R= 7×6/22

displacement= 2R

= 12×7/22

= 3.81
