Question

A partical moving in a circle of diameter 5m. Calculate the distance covered and the displacement when it completes 3 revolution.​

Answer 1

Answer:

5 metre plus 3 regulation is equal to 8 metres then complete the displacement when it complete 100 KM

Answer 2

SOLUTION :

diameter = 5m

radius = 2.5m

distance in 1 revolution = 2 (pi) r = 2 * 22/7 * 2.5

distance in 3 revolutions = 3* 22/7* 2* 2.5 (we could take the value of 22/7 as 3.14)

                                 = 3* 3.14* 5 = 9.42* 5 = 47.10   

as the body comes back to the same position the displacement is 0
