Question

A body is moving in a circular path of radius 2m. It completes one round in 2s.
What will be its speed and displacement?
​

Answer 1

Step-by-step explanation:

displacement =0 m

Answer 2

Answer:

Gɪᴠᴇɴ :-

Radius (r) of circle = 7cm

Time taken (t) to travel 1 round = 2 s

Tᴏ ғɪɴᴅ :-

Total distance (d) travelled by body

sᴏʟᴜᴛɪᴏɴ :-

Now,

✞ According to Question :-

➠ Distance covered by body = Circumference of Circle

We know that,

 Circumference of Circle = 2πr  

➠ 2πr = 2 × 22/7 × 7

➠ 44 cm

Hence,

➠ Circumference of Circle = 44 cm

Therefore,

➠ Total distance(d) covered by body = 44 cm
