Question

A particle moves in a circle with O as the centre and AO=OB=14cm .It starts from A. Calculate the distance covered and the displacement when it reaches B.

Answer 1

Answer:

Step-by-step explanation:

We have OA = 14 = OB

THEN OB AND OB IS THE RADIUS,

ITS TARVEL ON SEMICIRCLE,

DISPLACEMENT =14+14=28

DISTANCE =Pi R

= Pi × 14

= 14 pi
