Question

a body travelling on circular path of radius 10 m find the distance and displacement when body cover half cycle​

Answer 1

HEY MATE !!!☺☺

distance= 2πr+2r

=2×22/7×10+2×10

=440/7+20

=62.85+20

=82.85

displacement is the shortest distance between the initial and final position...

according to question:

body covers half cycle

=> displacement =diameter

=2× radius

=2×10

=20

HOPE IT HELPS!!☺☺
