Question

Q2. A body is boving on a circular path of radius 10 m.calculate the distance and displacement covered
by the body in one fourth round​

Answer 1

Explanation:

The distance of the overall motion will be given as

2▲r since its a circular track

Now the radius (r ) is 10

and the value of ▲ is 3.14

so,

distance = 2×3.14×10

=20 ×3.14

=62.8

NOW THE DISTSNCE IS 62.8 m

dist. of 1/4 will be

1 × 62.8

4

15.7m

SO THE DIST. 1/4 IS 15.7 m

DISPLACEMENT

LOOK THE DISPLSCEMENT IN ONE-FOURTH ROUND WILL BE 20 METRE

SINCE THE BODY HA S COVERED ONLY 1/4 THE DIST.

THE DISPLACEMENT WILL BE THE SHORTEST DIST. I.E RADIUS IS THE DISPL. WHICH IS 10 + 10

IN THE ABOVE GIVEN FIGURE U CAN UNDERSTAND THIS SITUATION

PLEASE FOLLOW ME HOPE U UNDERSTAND THE ANSWER . BYE
