Question

A body cover the distance of L metre along a semicircular path. Calculate the magnitude of displacement of the body and ratio of distance to displacement.

Answer 1

hello swetha dear friend again here's your answer....
in a semicircular path when a body travels.... it covers L metres.....
now we know that the distance I. e of semicircle is π×r ((taking it as 1)))

now the displacement would be 2×r (((taking it as 2))
now the ratio of distance to displacement would be
.....

(π×r) / 2×r == π\r


now if the value of r is known to you, you can calculate the answer.... by taking π= (22/7) /r...

Hope it helps you...
