Question

A particle is moving moving in a circular of radius 14m . The displacement after half circle would be?

Answer 1

Answer :

A particle is moving in a circular path.

Radius of circle = 14m

We have to find displacement of particle after half circle$.$

◈ what is displacement ?

➝ Displacement is defined as the shortest distance b/w initial and final position of journey.

➝ It is a vector quantity having both magnitude as well as direction.

ATQ, Particle covers half circle. After half circle, Particle will be at diametrically opposite to the initial position

Therefore,

Displacement of particle will be = 2r

• 2r = 2×14 = 28m

Answer 2

Answer: 28 m

Given:

$\sf Radius\:of\:the\:circle(r)=14\:m$

To find:

$\sf The\:displacement\:after\:half\:circle.$

Explanation:

$\sf ``Displacement\:is\:the\:shortest\:distance\:taken\:by\:an\:object\:from\:its\:initial\:position\:to\\\:its\:final\:position."$

$\sf According\:to\:the\:question,$

$\sf The\:particle\:moves\:around\:the\:half\:circle \therefore$

$\sf The\:shortest\:distance\:will\:be\:the\:diameter\:hence,$

$\sf Diameter=2\times r$

              $\sf =2\times 14$

            $\boxed{\sf =28\:m}$

Therefore, the displacement after the half circle will be 28 m.
