Question

A particle moves Around a circular path of radius 14cm. Find the distance travelled by the particle when (I) a half circle (ii) three complete circles. Also find the magnitude of the displacement.

Answer 1

Answer:

=14π,,,=84π,,,,0

Explanation:

is

distance travelled the half of circle =(2πr)/2

=πr

=14π

three circles completely so,

=3(2πr)

=6πr

=6×14π

=84π

displacement of object is starting and ending point is same so the displacement is become 0
