Question

10. STARTING FROM ONE OF THE VERTICES OF A REGULAR HEXAGON , THE PARTICLE COVERS THE THREE SIDES OF THE REGULAR HEXAGON IN ORDER . WHAT IS DISPLACEMENT OF THE PARTICLE DURING THIS MOTION [GIVEN THAT THE SIDE OF THIS REGULAR HEXAGON IS 'a ' units.] ? *
1 point
4a cm
3a cm
2a cm
a cm

Answer 1

Answer:

2a

Explanation:

as it is a regular hexagon , interior angle = 120°

let starting point = A

ending point = D

displacement= AD

in triangle AOB , all angle are 60°

hence equilateral triangle

therefore AO = AB = a

similarly OD = CD = a

displacement = AD = 2a
