Answer 1

SoLuTiOn :

⏭ Given:

✏ A particle is moving in circular path of radius r.

⏭ To Find:

✏ The displacement after half a cycle ?

⏭ Concept:

✏ Displacement is defined as the shortest distance between two points.

⏭ Calculation:

✏ Please, see the attachment for better understanding.

• Displacement = 2r m

⏭ Additional information:

✏ Displacement is vector quantity.

✏ S.I. unit of displacement is m.

✏ Relation between path length and displacementbis given by

$\orange{ \bigstar} \: \underline{ \boxed{ \bold{ \sf{ \pink{displacement \leqslant pathlength}}}}} \: \orange{ \bigstar}$

✏ Displacement can have positive, negative as well as zero magnitude.
