Question

A body moves round a circular path of radius 7 metre twice. The distance travelled and displacement are respectively ​

Answer 1

Answer:

Displacement = Diameter = 2× radius = 2×7=14m

Distance travelled =

2

1

× circumference

=22m

Answer 2

2*circumference=distance travelled

therefore 2*2*22/7*7

=88m

displacement=2*radius

2*7

=14 meters
